HOLY CRAP I THINK I'M IN LOVE. 
 Arin and Kestrel are just...PERFECT. I SHIP IT LIKE FEDEX. 
 It's about Kestrel, a rich daughter of a general who stumbles upon a slave auction. Turns out the slave could sing and she just HAD to win. But the slave isn't really what he seems.. 
 Arin is actually a spy for another country, and the auctioneer, Cheat (yup that's his name), is running the entire operation. Arin only became Kestrel's slave in order to get info on the general, but it takes a turn for the worst when Arin starts falling hard for Kestrel--and same for her. 
 I haven't felt this many...feelings for a character since I read Clockwork Angel (Jem Carstairs). Arin was just so incredibly amazing! I thought he would NEVER sing. I knew he could! 
 Kestrel's move at the end was confusing. Is she really going to marry Ronan?!
