This book is a light humorous adventure/quest. 

Brandsome the Unicorn lost his horn. He hires a PI named Twig, half-dragon/half-elf, who takes the job and promises to find the horn in question and bring it back. 

Being put down as a collateral for down payment, Quinn, the unicorn's human sex slave, takes on the role of a side-kick to Twig.

After three years of slavery and abuse, Quinn is happy for a short break, even more so because he adores his handsome new (if temporary) master. Of course, there are flashbacks and discussions of slavery under unicorn's hoof, but Quinn is living in the moment and enjoying his short freedom, not wanting to dwell on his misery. Twig treats him like an equal, at the same time being a bit on over-protective side due to his dragon-half mating surges. Twig Starfig is tough and rough, but knows firsthand how the rest of the world treats those who don't fit in it perfectly. 

The odd couple - a plain non-magical human pet and a half-breed - travels around the realm, playing dangerous card games with elves, boarding ghost ships, fighting zombies, drinking tea with cyclopes and making acquaintances with demons in penis-shaped castles (yep, that's a thing!). 

There is a bit of angst in the end, seeing how Quinn can't go back to Brandsome-the-Unicorn, not if Twig has any say in it, but mostly this book is about adventure and how it brings two odd creatures together. Love conquers all, they say =) Well, that and a very influential father-elf ;)

Frigging brilliant! My only complaint is that Kaleb is not suffering the change of scenery enough. He must have had friends, he must have had hopes and ambitions and plans, like being in college, obtaining freedom from his father. Maybe the reality is yet to settle in? :D

Looking forward to the next installment.

PS 
There are problems with editing, but I am choosing to ignore them since they were not too bad.
Mixed up "he, she" in reference to Kaleb's trans male brother drove me bonkers. There should be "He" in this book with this particular set of characters, no way around it. 

Book, I am very upset with you. Your meager 407 are the longest 407 pages I've ever read. Ever. Even "1001 Nights" wasn't that long when I read it last. 

If it wasn't for the empty banter between the characters and the small pockets of cute nothingness or dull brooding or any other unnecessary details that can be easily done outside of the book (like little ficlets), the whole reading experience would have been much more pleasant.

Rest in peace now. I am glad I am finally free of you.

PS
It's not a bad story, just the way it's told that didn't agree with me.

For all its faults and plot holes and patches and more of the same, the series is extremely engaging. 
Give me MOAR!!!

sirisly, im a frigging addict @.o
