-->''All who are true creatures will help where they can. As to the hounds, when they hunt--do not run.''

''The Hounds of the Morrigan'' is a fantasy novel from 1985, written by Pat O'Shea. It's [[DoorStopper big]], it's [[SlidingScaleOfIdealismVersusCynicism whimsical,]] and it contains more references to [[Myth/CelticMythology Irish Mythology]] than you can shake a stick at. The very plot itself revolves around the Celtic Goddess of War trying to absorb an ancient demon into her soul so that she becomes unstoppable.

Pidge--Patrick, in full, but everyone calls him Pidge--is an ordinary-if-bookish ten-year-old boy living in the Irish countryside with his little sister, father, and aunt. One day, while biking through the city, he stumbles upon an old book shop and finds an ancient tome. On one page is a drawing of a horrible serpent, the very image of which itself fills him with dread. Meanwhile, one of his neighbors rents out his spare greenhouse to a pair of beautiful but sinister women who ride around on motorcycles, who claim to be artists. The two are indeed related: That night, Dagda, the God of all that is good, tells him that the book contains the serpent Olc-Glas, a horrible beast [[SealedEvilInACan imprisoned there long ago.]] The two old women are Macha and Bodbh, and are part of the Morrigan--the Goddess of War and Discord and Death herself. They are out looking for the serpent themselves, because, if they add his poison to theirs... [[TheEndOfTheWorldAsWeKnowIt Well.]]

Olc-Glas is too powerful to be dissolved by anything but the Morrigan herself. But there is a way: Long ago, the great hero Cuchulain spilled a drop of her blood onto a pebble. If they can find that pebble, with its single drop of blood, they can use it to destroy Olc-Glas. But if The Morrigan finds it first, not only will she stop them from destroying the serpent, she'll get him for herself.

The Dagda chooses Pidge and his little sister Brigit to find it, on the grounds that they are brave enough, and clever enough, and alone true enough to do what is right instead of trying to use the serpent's power for themselves. But the Morrigan and her sisters have sent their dastardly hunting hounds after the two siblings, as they brave the world of Celtic myth in search of the stone. Luckily, all creatures good and light are looking out for Pidge and Brigit. But is it enough to keep the hounds away until they can find the pebble and destroy the serpent?

Despite its great (almost 700 pages!) size, the book is told in a lyrical fairy-tale style generally geared at children (and anyone who loves a good yarn). It contains NightmareFuel and SweetDreamsFuel in equal measure, though it remains firmly on the "idealistic" scale of the SlidingScaleOfIdealismVersusCynicism.

%%* TheFairFolk
* FlowerMotifs: Daisies are a recurring theme, because they are the flowers of Angus Og, the God of Love.
* FoodPorn: In writing, as the world of the spirits is so full of tasty treats you'll want to jump in and take a bite yourself. We have specially-seasoned scrambled eggs, sausages abound, wonderful fruits, and even the Swapping Sweets, which are both yummy ''and'' useful.
%%* FunetikAksent: A number of characters have them.
* GettingCrapPastTheRadar: Brigit tries to do this with, "Where's that bloody pebble?!" Pidge catches her and gives he a scolding.
* GiantSpider: Mawleogs and his clan are a whole family of them! However, they're firmly on the good side, and they love acrobatics and singing songs.
* GodInHumanForm: [[spoiler: Boodie and Patsy, who are really Brigit (the goddess) and Angus Og, respectively.]]
* {{Gorn}}: The final battle is almost ''insanely'' bloody, such that if the book were to be filmed, it would probably get a PG-13 rating ''at least'' for that scene alone.

* KidHero: Pidge and Brigit. Brigit is only 5!
* LaserGuidedAmnesia: This is done to Pidge and Brigit at the end, as a kindness to them, so that they can walk completely in the human world without being troubled by memories or wanting to return to Faerie. They meet the red fox again and even give him sausages to eat, and are troubled by an odd sense they've met him before, but Cooroo doesn't let on.

%%* PrecisionFStrike: "You're a ''damned'' fool."
* QuickNip: The Sergeant tends to nip into his stores of confiscatched hootch for... less-than-professional reasons.
%%* RealityChangingMiniature: The table the Morrigan sisters use.
* RoadSignReversal: The very first trick Macha and Bodhb try to pull on Pidge. It's much eerier than the usual examples, because they have magic.
%%* SealedEvilInACan: Olc-Glas. His release is something they want to ''prevent.''
%%* SealedGoodInACan: [[spoiler: The Irish Elk.]]
* SortingAlgorithmOfThreateningGeography: Two children living in modern Galway are drawn into the other Ireland of myth and legend. As their quest progresses, the mythological landscape is at first funny, absurd, Disney-Oirish, even, with hints of something deeper beneath. It gradually becomes darker, bleaker, more sinister, as the life-or-death nature of their quest asserts itself, and the final showdown with the forces of Not-Good takes place in a Mordor-like bleak and barren place. It's like going from a leprechaun Hobbiton to a Mordor ruled by the Morrigan.
* SugarBowl: The land in the hidden valley. The more [[{{Oireland}} Disney-Oirish]] aspects and locations of the quest.
* TalkingAnimal: Most animals in the other world talk. Even the insects!

* TomboyAndGirlyGirl: Melodie and Breda are a villainous version, with Melodie being the sweet/romantic one, and Breda being the more blunt one.
* TrademarkFavoriteFood: Cooroo loves sausages.
%%* TheVeryDefinitelyFinalDungeon: The Third Valley, ''definitely.'' And, possibly, [[spoiler: the Morrigan's labyrinth, though Mossie Flynn takes care of that unintentionally.]]
* VictoryGuidedAmnesia: [[spoiler: Although the Dagda takes away Pidge and Brigit's memories, he favors them after. Cooroo comes back as their friend, though he can no longer talk to them, and Dagda sends them rainbows just for them.]]
%%* WeirdnessCensor: The Sergeant attempts to maintain his for quite a while, blaming poteen, before he finally realizes there's nothing he can do.
* TheWorldIsJustAwesome: Pidge has a moment of this when he first beholds [[spoiler: the second valley.]]
