Blood Sisters / Cate Quinn.

"You'd die for your best friend. But would you kill for her?" --front cover.

The tiny outback town of Dead Tree Creek is a rough place - and the locals are even rougher - but they've never seen anything like this . . . When a man is found gruesomely murdered in the local pub, all fingers point to the backpackers working behind the bar that night - two American girls who skipped town before the body was discovered. Despite all the evidence against them, rookie cop Tara Harrison knows there must be more to this case than a pair of sorority sisters who couldn't take a joke. She's determined to uncover the truth, and is soon on the trail of a devastating secret that could tear her hometown apart. But sorority sisters Lauren and Beth have their own dark secrets and they've made an oath to take them to the grave - which they will, all too soon, unless Tara can stop it . . .
