Shipwreck Island #4: Found
In the thrilling final book of S.A. Bodeen's middle-grade Shipwreck Island series, it's up to a young girl to save her shipwrecked family from a time-traveling "curator" of souls and a treasure-hunting criminal—and get them off the island!
Sarah Robinson and her family are shipwrecked on a remote and mysterious island. Their food is scarce and there's no sign of rescue. They have seen strange creatures, rescued a mysterious girl, and found the Curator, who has captured Sarah's father and stepbrother to use in a bizarre time travel experiment. And then the only man who knows about their island comes back—he's looking for buried treasure, and won't leave without it, even if it means leaving the Robinsons stranded.
Time is running out. They must get off the island.
