Two solar eclipses. Two missing girls.

Sixteen years ago a little girl was abducted during the darkness of a solar eclipse while her older sister Cassie was supposed to be watching her. She was never seen again. When a local girl goes missing just before the next big eclipse, Cassie – who has returned to her home town to care for her ailing grandmother – suspects the disappearance is connected to her sister: that whoever took Olive is still out there. But she needs to find a way to prove it, and time is running out.
