DEVIL'S KISS by Sarwat Chadda

This is an interesting book and character of Bilquis aka Billi, the only female Knights Templar at the age of 15. The archangel Michael aka Mike Harbinger is out to repeat The Tenth Plague in London in order to bring people back to their faith and to God.

In this book, The Templar are a rag tag group group of 5 or 6 Londoners consisting of one young 15 year old girl who's father is very cold and distant, only focusing on her training as a Templar. Billi resents all this training and wants to be a normal girl when she meets Mike just as her former friend and fellow Templar Kay comes back into town. Kay has changed from that gawky boy he was and is interested in getting closer to Billi. But she is interested in the mysterious Mike. Only to find out that Mike is the Archangel of Death and is using Billi to get to The Cursed Mirror, the last of the Holy relics not lost and still in the Templar's possession.

When Billi realizes what Michael is up to, she must step up to the plate and become the Templar she never wanted to be, but is destined to become.
