Young Blood. Meg Cabot Mediator

Suze should be spending the summer vacation at the beach. Instead, she s been forced to get a babysitting job at a swanky resort. She d expected to look after some boring brat, so Suze is surprised to find that her charge is actually a budding mediator - with a totally hot older brother. Not that Suze s head could be turned by some guy - she s pledged her heart to Jesse, the most gorgeous ghost ever. But, it s tough when the boy you love doesn t seem to love you back, and it s even tougher when you think you ve found his 150-year-old grave in your backyard. Suze knows it s dangerous to dig up the past, but how can she focus on babysitting when she could be close to discovering who killed Jesse?
