Time Sight — Lynne Jonell

Castles, battles, the ancient Scottish Highlands, and a boy who is determined to bring everyone safely home combine in this absorbing middle grade time-travel adventure.

Will's mother is in danger overseas, and his father must find her, so Will and his little brother are packed off to relatives in Scotland. Will feels useless. He can't save his mother. He can't help his father. And when he tries to amuse his brother on the plane ride, he can't even locate the images in Jamie's book―the hidden pictures that everyone else can see. Once at the family's ancestral castle, though, Will tries again. And as he delicately adjusts his focus, suddenly his eyes tune in to a different visual frequency―the past.

Looking back five hundred years is interesting . . . at first. But when Jamie impulsively leaps through the opening in time, Will and his cousin Nan must follow, into a past so dangerous that Will isn't sure how he will get everyone safely home.
