History Main / TieInNovel

These novels are usually written in a very conservative style. You're unlikely to encounter one written in the style of Margaret Atwood or Marcel Proust.

These can be {{novelization}}s of episodes or "untelevised adventures".

* The ''Series/{{Castle}}'' tie-ins, rather than being books about the series, are the books that Castle is ostensibly writing ''in'' the series.

* ''ComicBook/SpiderMan'': Has had a bunch of novels in the 90s by Creator/DianeDuane. More recently, Creator/JimButcher has been writing them as well.

* Franchise/{{Batman}} -- In addition to the {{novelization}}s of the movies, and even the comics (The ''ComicBook/{{Knightfall}}'' storyline was novelized), Batman has had several stand alone novels like ''The Ultimate Evil''.
* Franchise/{{Superman}} -- Has had tie-in novels since the 40s.
* Franchise/SpiderMan -- Had a rash of novels in the 90s by Creator/DianeDuane. More recently, Creator/JimButcher has been writing them as well.

* ''Anime/{{Pokemon}}'' had a couple of picture books based on various episodes such as "Bye-Bye Butterfree" and "Attack of the Prehistoric Pokemon".

The tie-in novel is literature involving the characters of a TV series, film or other work and usually written by some author you've never heard of[[note]]Sometimes they deliberately work under pen-names to keep their "serious" work apart[[/note]]. Pretty much anything can have a tie-in novel. They're often compared to authorized {{fanfic}}, in that they're usually not part of the main continuity, do things that would never be considered in the original, and are widely variant in quality. If a series is exceptionally popular, the tie-novels may have their own micro-continuity. If it's mega-popular, expect them to occupy their own ExpandedUniverse. Expect tie-in novels by the same author to refer to events in their other novels.

* The Heisei-era ''Franchise/KamenRider'' got their own series of tie-in novels, variously serving as prequels, sequels, untold stories, or alternate takes on the original shows. In terms of content, it's a mixed bag; most are disregard by fans for trying to be DarkerAndEdgier ([[spoiler:''[[Series/KamenRiderBlade Blade]]''[='s=] focuses on a now-immortal Kenzaki trying to kill himself, while ''[[Series/KamenRiderFaiz Faiz]]''[='s=] depicts Kusaka raping Mari and ends with him getting his limbs hacked off by Kiba and being taken in by a stalker a'la ''Literature/{{Misery}}'']]), while ''[[Series/KamenRiderDecade Decade]]''[='s=] is full of glaring continuity errors ([[Series/KamenRiderDenO Momotaros]] being portrayed as [[BoisterousBruiser quiet and polite]] is just the tip of the iceberg). The ones that are generally well-regarded seem to be official canon, or at least referenced in official media; ''Series/KamenRiderDrive''[='s=] novel is the first part of a story that concludes in Mach's stand-alone movie, while [[Series/KamenRiderDouble Philip's Kamen Rider Cyclone]] form appeared in the video game ''Super Climax Heroes'' as an AssistCharacter for Shotaro's Kamen Rider Joker.

* ''Website/SCPFoundation'' has the LightNovel ''Iris Through the Looking Glass'', written by Akira (of ''LightNovel/SasamisanAtGanbaranai'' and ''[[VideoGame/EnsembleStars Ensemble Series]]'' fame) and illustrated by Sidu (of ''Franchise/KagerouProject'').

* ''Series/WelcomeBackKotter'' has five or six of them.

* ''Wiki/SCPFoundation'' has the LightNovel ''Iris Through the Looking Glass'', written by Akira (of ''LightNovel/SasamisanAtGanbaranai'' and ''[[VideoGame/EnsembleStars Ensemble Series]]'' fame) and illustrated by Sidu (of ''Franchise/KagerouProject'').
