Everything about this book intrigued me after reading the summary. I liked the idea of The Scorpio Races which was described as "Riders attempt to keep hold of their water horses long enough to make it to the finish line. Some riders live. Others die." You have no idea how big of an understatement this is unless you read how brutal and dangerous the capall uisce can be. 
 I loved the the world building Stiefvater used; the way she wrote about the water horses, the island being 
 apart from the other places like America or the mainland, the Connollys as a family, and the way the whole town was described, especially the festival and different celebrations they did. 
 Another thing I liked was that there wasn't a love triangle! Also, the fact that it wasn't instalove between Puck and Sean, it wasn't even love at first and they were just strangers who spoke and then friends, and they kissed (view spoiler)[(one of my favorite parts near the end of the book was when someone asked Puck "You are a pair, right?" "In training" or something along those lines.) (hide spoiler)] 
 Although I am sad that there isn't a sequel to this spectacular book, I am glad with how things ended. Sure I would have liked to see where Puck and Sean went on after this, did they get closer and start dating, did Corr get better and (it seemed that he got his attention on Dove back there as a possible mate) so what hapenned between him and Dove, were Puck and Finn able to make ends meet and have fun, etc. 
 Either way, this is one of the best books I've read this year (and it's barely January!). Highly recommend it, it's good to read a novel that isn't part of a series every once in a while.
