Til the End of Time — Angela Sage Larsen

In Book 5 of the Fifties Chix series, Judy's dream may have come true; Bob Jenkins could finally see her in a new light if she gets cast as the lead in a play. Bev is still walking on air after her performance with the boys' baseball team gets her accolades; Maxine is championed as a writer and an activist; Mary may have finally found peace with her family and James O'Grady; and Ann may have convinced her cousin to move to the States. The Fifties Chix could be about to get everything they ever wanted ― so why do they still feel out of place? With a revelation that will make their world come crashing down around them, their social studies teacher may destroy everything they worked for. The Fifties Chix, now more than ever, must test the strength of their friendship. Will they work together to save their teacher and find their way home, or will they lose each other forever?
Brace yourself for a wild ride through the past to the future and back again as the Fifties Chix solve their time travel mystery and discover the truth about love and friendship.
