StarPassage: Honor and Mercy: Book 3 by Clark Rich Burbidge

They have a new patient in rehab who is without hope.  As they try to encourage him, they have no idea he carries a secret.

P R by the Book sent me a copy of this book to read for review (thank you).  It has been published and you can grab a copy now.

Ronnie has been taken over by a traveler.  This traveler has plans to change the outcome of the Civil War and he's going to use the other kids and their star to do it.

As they go where the star takes them, they never know what to expect.  But it doesn't take them long to figure it out when they find themselves on the battlefield.  How will they stop Clynt?

These stories are fantasy with some historical facts interspersed.  They're not boring and you always wonder where they are going next.  One event in this book was a little far-fetched but it's all part of the fantasy.
