The Slayer Chronicles: First Kill by Heather Brewer

Heather Brewer has yet again impressed us with the debut of her newest series, First Kill. This series is centered around Joss, a character in her previous series, The Chronicles of Vladimir Tod. This new series is her attempt to prove to us all that there are several sides to every story and each side is just as important as its counterpart.
From a young age Joss had showed abilities far beyond other boys his age. This set him apart from everybody else. After his younger sister's terrible murder, he learns about the Slayer Society and decides he wants to take part in order to avenge his sister's wrongful death. Joss must face many near impossible obstacles and the wrath of his uncle in order to become the youngest slayer in history.
