HOLY CRAP. I don't know why I waited so long to read this, but I am so glad I finally did. Instead of being just from Sydney's perspective, "The Fiery Heart" is from Adrian's as well. Getting to see inside his head as his relationship with Sydney blossom and his problem with spirit deepens is interesting, to say the least. As Adrian and Sydney's relationship intensifies, the danger of Sydney being caught and consequentially "re-educated," and she rushes to find a way to combat the Alchemist's tattoo effects. Adrian and Sydney's newfound relationship isn't the only event going on in the book. There's also an exploration of a new way to fight Strigoi, and Adrian gets to step up to the plate with the use of spirit. The entire book is a heart-pounding adventure from start to finish and the entire series is a must read for anyone a fan of Vampire Academy.
