Solace is one of the Rare - people with supernatural Tricks who do their best to survive unnoticed. Raised in foster care, she understands little about who she is until her approaching birthday, when an encounter with a faceless man sends her off on her own.
She finds herself drawn to a small group of similar people subsisting in a squat in Sydney, among them Aleatory, who can summon lost things, Manx, who can turn into a cat, and Glide, who Internet seraphs both time and universal.
Solace herself is a vampire - by birth rather than bite, making her unique - who slowly realises that she is an important target for her family's old foes, bringing danger to her new friends.
This is in the realm of young adult urban fantasy, recommended for 15+.
