The Devil's Triangle by Toni DePalma

Summary:
When 17 year old Cooper dies in an attempt to burn down his school, he finds himself in the afterlife. Lucy, the Devil's sister who has crossed party lines, decides to give Cooper another shot at heaven. The deal? Cooper returns to Earth and has to find a girl named Grace. The rest is up to him.

While Cooper figures out his mission, he's thrown into the life he's always wanted. Great parents, a spot on the Varsity football team and a real future are all within reach. But what he really wants is Grace, a feisty girl with an abusive boyfriend who can pound Cooper into pulp if he doesn't watch out.

While Lucy plays demonic-puppeteer, clues to an unknown past between Cooper and Grace start to unravel. Cooper discovers that what's keeping him and Grace apart is far more sinister than anything this bad boy could have ever imagined.

My thoughts:
I saw this cover a while back and loved it. Then I was approached to review the books, so of course I agreed. I love books where the Devil is a character, and this may be the first one I've read where the Devil's sister is a character. So I loved that spin. Especially since Lucy is going against her brother by helping Cooper get another shot at Heaven.

I enjoyed the characterization. There are glimpses of Cooper's previous life when he burned down the gym and we get to see how different things are for Cooper in his new life. The contrast was done really well and added to his character's depth. 

While he tries to get close to Grace, things get complicated and more dangerous for Cooper. She's got a boyfriend and he's trouble. I wish we would've gotten to see more of Cooper and Grace, but it seems like we may get to see it in the next book.

Overall, it was an enjoyable and quick read.

Just for fun:
Would you trust the Devil's sister to help you get into heaven?
