Theo knows the Rule, just as every kid from the year fifteen billion and seventy-three does: When using your TimeMaster JumpMan for routine time travel, DON'T TOUCH ANYTHING. And usually, when traveling to routine JumpSites like Three Seconds After the Big Bang or the Building of the Great Pyramid, this is no problem. But Theo's latest TimeJump is anything but routine. First, this Jump has put him in the early twenty-first century, of all places. Second, he has found himself visible to Genevieve and Jules, just as Jules is about to ask Gen out on a date. And finally, his JumpMan won't send him back to where he came from. 
Will Theo get back to his own time, without disintegrating? Will the very fabric of space and time be torn to shreds? And most important...will Jules ever be able to ask Gen out on that date? Only time will tell in this roller-coaster ride of action, humor, and suspense from international best-seller James Valentine.

When James Valentine discovered Guale, he was a young man with a camera and a mission. This hauntingly beautiful collection of photographs and poetic prose resulted from Valentine's love affair with Guale and its sacred landscape. The Guale Indians lived, hunted and fished amidst the barrier islands of the Georgia coast. That jewel like chain of islands still possess a unique diversity of sub-tropical coastal life and landscape.
