A Circle of Time — Marisa Montes

“An enjoyable, compelling read. Much like Caroline B. Cooney's Both Sides of Time” from the author of Los Gatos Black on Halloween (School Library Journal).
 
“I helped you. Now you help me.”
 
As fourteen-year-old Allison Blair lies comatose in the hospital, she hears in her head the voice of Becky Lee Thompson, pleading for help and pulling Allison back in time to 1906 -- and into Becky's body. But why? Is it to prevent Becky's tragic death, or the death of Joshua, the boy who loves her? Allison must remain in the past -- fortified by her own growing feeling for Joshua, and Becky's will -- to make sense of the layers of mystery, blackmail, and mistaken identity so that history will be altered.
 
Becky's spirit struggles to keep Allison's body alive. Can Allison save Becky and Joshua and return to her own body before time runs out?
 
“Fans of both mysteries and time-slip stories will like the novel, which is liberally spiced with romance and melodrama, and clarifies a bit of intriguing and tragic California history.” -- Booklist
