If you loved Circle of Secrets, you will love The Time of the Fireflies! Larissa's family owns an antique shop. One day Larissa hears a phone ring, except it's one of the phones they sell to customers. One of the phones who's lines are disconnected. The voice on the phone tells her to find the fireflies and trust the fireflies. How was she supposed to do that? The real question was, how was she supposed to save her Mama and her baby sister who wasn't even born yet? She had to go back in time, and in doing so, traced her family's misfortune and tragedies all back to one thing. And you'll have to read the book to find out what it is. It was very sweet, and sometimes creepy, and I'd recommend it to grades 4-8, although it may be a little hard for younger readers. I LOVED IT!!!!!!
