A Trail Through Time: The Chronicles of St. Mary's series by Jodi Taylor
Sometimes, surviving is all you have left.
Max and Leon are safe at last. Or so they think.
Snatched from her own world and dumped into a new one, Max is soon running for her life. Again.
From a 17th century Frost Fair to Ancient Egypt; from Pompeii to 8th century Scandinavia; Max and Leon are pursued up and down the timeline, playing a dangerous game of hide-and-seek, until finally they're forced to take refuge at St Mary's - where a new danger awaits them.
Max's happily ever after is going to wait a while...
