Stone and Sand — Sibella Giorello

This was no accident…or was it?

Raleigh Harmon just won a coveted science contest, with the chance to compete for a $50,000 college scholarship. Great news, right?

Only her goofy aunt drives her to the contest in North Carolina, and as soon as they arrive, Raleigh realizes she's way out of her league. All the competitors are ruthless brainiacs. And she has no idea how to win this contest.

That suddenly changes when one of the competitors almost dies -- and Raleigh looks like a prime suspect for the attack. With forty-eight hours to solve the science riddle, can Raleigh also pick out the bad guy -- or girl -- before they escape the island? And what if the bad guy is the boy Raleigh really likes?

Stone and Sand is the third book in the Raleigh Harmon prequel mystery series, introducing the girl who will become a forensic geologist and FBI agent -- provided she survives the high school years.
