I first "read" this book via the audiobook version on Audible.com, and enjoyed it very much - a nice mix of stories with "kaiju" themes, and with a variety of good narrators. I decided to order a text copy to share!
While the theme is "kaiju", as in Godzilla and friends, the book goes more for the literal translation, "strange creature"; while all of the stories feature immense monsters of some kind or other, they range widely from the classic city-stomping type to ancient Greek demi-gods. Among my favorites:
"Big Ben and the End of the Pier Show" by James Lovegrove: this one looks at a kaiju-vs-giant-mecha battle from the viewpoint of the owner of a nearly-defunct pierside attraction.
"Day of the Demigods" by Peter Stenson is from the viewpoint of a kaiju - a very hunky one, at least in his own mind, though his combination of features results in a rather unfortunate and goofy profile. This doesn't stop him from wreaking havoc while trying to impress the girls, though!
"The Lighthouse Keeper of Kurohaka Island" by Kane Gilmour has an old man introducing his son to his ancestral duties as keeper of the place where the kaiju go to die - and where at least one great kaiju, defender of humankind, rests until it's needed again.
"One Last Round" by Nathan Black features a team that pilots a giant mecha, and who have just been fired - but when a huge alligator-like kaiju attacks New Orleans, the team hijacks their mecha and goes to the rescue.
"Heartland" by Shane Berryhill takes a very different tack: here, a remote community preserves the peace by offering sacrifices to the kaiju that lives in their quarry. One mother wants to save her daughter from the selection, and winds up facing an incredibly painful choice.
"Devil's Cap Brawl" by Edward M. Erdelac is an entertaining Wild West take on the theme. Here, miners awaken an ancient monster, which can only be stopped by a powerful monk - who happens to be working as a humble miner until he's needed. [Details of his training, scars, etc., suggest an homage to another famous Shaolin monk in the old West...] The battle is epic!
"Of the Earth, Of the Sky, Of the Sea" by Patrick M. Tracy and Paul Genesse is set in Japan, and has a sect of priestesses working with the sacred dragons of each element to battle a deadly foe from the myths of a foreign invader. Marvelous details here, from the epic battles to the growing friendship between the priestess and the general. Mess with elemental forces at your peril!
"The Banner of the Bent Cross" by Peter Clines is set in WWII, when the Axis has somehow acquired a ship out of legend; to battle it, a team of soldiers and scholars must find the resting place of a pair of monsters from Greek myth - but can they control them if they wake them?
"Dead Men's Bones" by Josh Reynolds is set during WWI, where the Germans have constructed an enormous monster from the bodies of the fallen.
"Stormrise" by Erin Hoffman takes a more SF turn, with the kaiju here being quite different than in most of the stories. Its futuristic setting and unusual twists impressed me.
"The Great Sea Beast" by Larry Correia introduces a boy who's the only survivor from his father's ship, destroyed by a hideous kaiju - but nobody believes that he saw the thing, and it is assumed that his father's incompetence sank the ship. Struggling against this loss of face, he has a rough life, but eventually he gets a chance to confront the beast again and, perhaps, clear his family name.
And there's much more - a really good collection!
