Stolen Songbird by Danielle L. Jensen

This is one of those books where the first half deserves one rating while the second gets a slightly higher one.  It started off at a run, throwing the reader into the environment and the characters, but quickly slows to a dead stop.  It's basically beauty and the beast with trolls.  But not like tiny, live under your local bridge-type trolls.  These trolls are basically fairies (I am placing heavy bets on this reveal in coming books) with slight abnormalities cause by years cursed to confinement within a mountain.  The main heroin, Cecile, is very likable.  The relationship between her and the troll prince is intriguing and genuine.  The conflict between full-blooded trolls and half bloods is trying to hard but is well meaning.  I think I will continue the series.

Final Recommendations: if you like magical creatures, kidnappings, strained romantic entanglements, crewel kings, and lots of unanswered secrets
