I think Jane Yolen out did herself and hit a homerun, with Hearts Blood, an extraordinary book. In this vivid storyline, a boy named Jakkin risks his life, his dragon Hearts Blood's life, and his dragons hatchlings life, to save his love Akki. The risk was being involved with the rebels who are against the republic and the republic send people down to the colony to keep everything in order but then the rebels exploded the side of the Major dragon pit called in the city of Rokk. The people from the republic think Akki and Jakkin did it so they flee. Will the republic find them or not, what will happen to Jakkin and Akki? read Hearts Blood to find out. I've read the whole series, and many of her other books such as; Devils Arithmetic, The rest of the Pit Dragon trilogy, Merlin, and Armageddon Summer. Her word choice was great because she uses words that you wouldn't normally know the meaning to, but when she uses them you do; such as, "Myriad of colors", and she is very imaginative in the ways she described the dragons.
I highly recommend this book to all young adults.
