->''I can't keep a secret. Never could...''

The ''Secret Series'' is a series by Pseudonymous Bosch, a mysterious LemonyNarrator, about two children who are not named Cass and Max-Ernest. Cass is a [[CrazyPrepared survivalist,]] while Max-Ernest has a condition (though no one knows quite what his condition is). One day, they are swept into the dangerous world of the [[SdrawkcabName Terces]] Society and the Midnight Sun...and the Secret.

There are five books in the series:
* ''The Name of This Book is Secret''
* ''If You're Reading This, it's Too Late''
* ''This Book is Not Good for You''
* ''This Isn't What it Looks Like''
* ''You Have to Stop This''

In 2013, the series was followed by ''Write This Book: A Do-It-Yourself Mystery''. While not directly a part of the ''Secret Series'', it directly references several characters and situations from it.

!!Tropes used by the novel:

* AlphaBitch: Amber comes up in the first books as well-intentioned although misguided, but later is revealed to be clearly this.
* AmbiguouslyGay: Grampa Larry and Grampa Wayne are never outright stated to be a couple. Just two guys who live together since a long time ago, bicker amongst themselves even though they clearly care a lot for each other and have a substitute daughter and granddaughter [[spoiler: and substitute grandson, in the fourth book]] together.
* ArchEnemy: Dr. L to Pietro.
* AristocratsAreEvil: Lord Pharaoh. Although not a real Lord (nor a real Pharaoh). The rest of the nobility aren't particularly noble either.
* ArtificialHuman: The Homunculus in the second book.
* TheBeautifulElite: The Midnight Sun usually has unnatural beauty, which they sometimes [[ScrewTheRulesImBeautiful exploit in their evil schemes]].
* BigEater
* BlondesAreEvil: Ms. Mauvais.
* {{Brainwashed}}: [[spoiler: Benjamin Blake, briefly.]]
* ButtMonkey: Max-Ernest.
* CassandraTruth Played with, Cass is a survivalist that always predicts disasters, but they rarely come true

* DrivenToVillainy: Dr. L.

* FootnoteFever
* GenreSavvy: Cass, survivalist and danger specialist, strives for it.
* GiveHimANormalLife: [[spoiler: possibly the reason Cass was put on her grandfathers' doorstep.]]
* HilariouslyAbusiveChildhood: Although his parents are well-intentioned, poor Max-Ernest has an unusual childhood to say the least. Both of his parents are absoultely certain that he or she is right, and the other is well-intentioned, but misguided. When Max-Ernest was born, they argued for several days about whether to name him "Max" or "Ernest". This argument lasted so long that the nurse threatened to put him up for adoption, name or no name. They then compromised, and then divorced. But they both still live in the same house, since the one thing they ''can'' agree on is that every child should be raised by both his parents. So they split the house in half and pretend the other half doesn't exist.
* HurricaneOfPuns The Jester is the very incarnation of this trope
* IdiotBall: You just ''had'' to [[spoiler: eat that chocolate]], didn't you?
* KnifeOutline: Used for intimidation in the third book
* LemonyNarrator
* LongLostRelative: [[spoiler: Dr. L for Pietro.]]
* MacGuffin: [[OnceAnEpisode Every book]] centers around either finding some ancient artifact, or keeping it away from the Midnight Sun.
* MadScientist: Most of the Midnight Sun, and their founder.
* MeaningfulName: [[CassandraTruth Cass]], done purposely, and is lampshaded.
** Max-Ernest [[spoiler: [[FunWithAcronyms , or should we say]] [[AuthorAvatar M-E?]]]]
*** WordOfGod says that it reflects how Max-Ernest tries to be funny, but strikes people off as highly serious. [[DontExplainTheJoke In other words, he is earnest to the max.]]
** Ms. Mauvais' name translates from French literally as "Ms. Bad" or "Ms. Evil"
* TheMole: [[spoiler: Benjamin Blake, briefly.]]
* MorallyAmbiguousDoctorate: Dr. L.
* MotorMouth: Max-Ernest. Also Cass (briefly) in the first book.
* MyBelovedSmother: Both of Max-Ernest's parents, in competition with each other.
* NarratorAllAlong: ''This Isn't What It Looks Like'' suggests that [[spoiler: Max-Ernest is actually Pseudonymous Bosch when he was young.]]
** [[spoiler: Confirmed in the epilogue of ''You Have to Stop This''.]]
* NephariousPharaoh: Lord Pharaoh is a prime example of this: evil, single-minded dedication to living forever and quite possibly taking over the world someday.
* NiceJobBreakingItHero: ''This Book Is Not Good For You'' could've been done differently if [[spoiler: Cass didn't open her big mouth regarding the Tuning Fork.]]
* PlatonicLifePartners: Cass and Max-Ernest.
* RedRightHand: All of the members of the Midnight Sun have gnarled, ancient hands that they hide under gloves.
* TheReveal: [[spoiler: The Secret itself, surprisingly, at the end of the last book. While it may seem to be just a joke at first "Why did the ibis cross the road? To get to the other side.", it's established that "the other side" literally means just that - as in, the afterlife]]
* TheSpeechless: Max-Ernest, while [[spoiler: Cass is in a coma.]]
* SuperSenses: Cass has excellent hearing. And Pseudonymous Bosch claims to have perfect vision.
* ThinkOfTheChildren: The reason Max-Ernest's parents, despite their divorce, remain in the same house [[spoiler: and the reason they eventually split up.]]
* ThisIsAWorkOfFiction: In ''You Have to Stop This'', the disclaimer reads "The characters and events portrayed in this book are fictitious. Any similarity to real persons, living or dead, is coincidental and not intended by the author. Of course, you know what they say about good intentions..."
* ThoseTwoGuys: Daniel-not-Danielle and Glob in the fourth book.
* TwoGuysAndAGirl: Cass, Max-Ernest, and Yo-Yoji.
* UnusualChapterNumbers: ''If You're Reading This, it's Too Late'' has the chapters in reverse order (starting with Chapter 34 and ending with Chapter 1) because the author hopes the book (and the secrets contained within) will explode like the countdown timer on a bomb. In ''This Isn't What It Looks Like'' there are normal chapters, but also negative chapters for Cass and what she's doing in the past.
* WholesomeCrossdresser: [[spoiler: Owen in book 4.]]
* [[WhyDidItHaveToBeSnakes Why Did It Have To Be Mayonnaise?]]
* WoodenKatanasAreEvenBetter: Samurai Yo-Yoji doesn't even need a real wooden katana, he kicks ass with a stick.
* WriteBackToTheFuture: [[spoiler: the trunk in book 4.]]
* VillainousBSOD: Dr. L when he realizes [[spoiler: Pietro is still alive.]]
