Frostblood is an enjoyable YA fantasy book which is both fast paced and romantic. It is a book of two halves which had a different tone to them, however the story was full of clichés and predictable. While the world building was good I would have liked other countries to be fleshed out a bit more.
Ruby is short tempered and has a lack of emotional control but is also kind and inquisitive. Arcus is moody and damaged both physically and mentally but he is also loyal and protective. My favourite parts of the book were the banter between Ruby and Arcus and how slow the romance was in building.
I enjoyed this book and am looking forward to reading the sequel Fireblood. I would recommend Frostblood to fans of The Storm Siren trilogy by Mary Weber and the Fairy Queen books by Amber Argyle.
