Hush, hush - Becca Fitzpatrick

A sacred oath, a fallen angel, a forbidden love...
This darkly romantic story features our heroine, Nora Grey, a seemingly normal teenage girl with her own shadowy connection to the Nephilim, and super-alluring bad boy, Patch, now her deskmate in biology class. Together they find themselves at the centre of a centuries-old feud between a fallen angel and a Nephilim
Forced to sit next to Patch in science class, Nora attempts to resist his flirting, though gradually falls for him against her better judgment. Meanwhile creepy things are going on with a mysterious stalker following her car, breaking into her house and attacking her best friend, Vi. Nora suspects Patch, but there are other suspects too - not least a new boy who has transferred from a different college after being wrongly accused of murdering his girlfriend. And he seems to have taken a shine to Nora...
Love certainly is dangerous... and someone is going to have to make the ultimate sacrifice for it.
