Double Cross (Twintuition, Bk. 4)

In this fourth and final book, tween twins Cassie and Caitlyn Waters are excited to be returning to their hometown, San Antonio, on a class trip. But as they reach their destination, trouble finds them as quickly as a vision, and one of their friends soon disappears.

Using their Sight and their street smarts to try and save the day, the twins also begin to see things they didn’t expect - a man in captivity who looks exactly like their father’s pictures. Could he really be alive? And can they use the clues they see to save him before it’s too late?
