What is the ending of Sent by Margaret Peterson Baker?

In England, the war is going on and right when they see Chip's uncle's horse collapse and die, they see his crown rolling and they see him dead, so Chip grabs the crown, yells,"I am king once again" and then as they yell "lets get back now" a man from the future uses his elucidator to zap them to JB and then when all of them are back, they (Katherine and Jonah) get sent to the 1400's with Andrea and a Bernese Mountain Dog named Dare, and Andrea is the first baby born in a small village and her name is Virginia Dare. Then they lose the elucidator in "sabotaged" and find out Virginia's (Andrea's) place has been ruined and IS ruins, they see a log with "Croatoan" carved into it and find out something shocking...
