The Last Apprentice #13: Fury of the Seventh Son by Joseph Delaney

This book is the final chapter in the series, and I gave it a rating of four out of five. Tom Ward is close to destroying the Fiend once and for all, but things start to go wrong. His friend, Alice, thinks she has found a way to defeat the Fiend without sacrificing her own life, but she may totally turn to the Dark in the process. The Fiend's followers are reuniting his head with his body, so he can come back to life. A powerful mage has arisen, and his magic may be too much for Tom to handle. The Spook is old and not as strong as in the past, and Grimalkin, the witch assassin, is near death herself. If things weren't bad enough, Alice informs Tom that a more terrible foe will ravage the land if the Fiend is somehow defeated. Tom turns to the vicious Boggart, Kratch, in a desperate moment, but feeding it some of his blood may prove to be his downfall.

You will need to read the other books in the series before reading this finale; you can search for the other books by typing Delaney or Last Apprentice in the box at the top left of this screen. The entire plot leads up to an epic battle between the spooks' forces and the Fiend's followers. Tom's character has a lot of internal conflict. He wants to defeat the Fiend, but he may be forced to battle his best friend to achieve it. He keeps important secrets from the Spook even though he doesn't want to. Tom's relationship with Kratch is a new twist to the plot.
