Mars Quake — Jon Batson

When astronomer Dana Wright thinks she has seen writing on Mars, she wants to take a look through a larger telescope. Senate aide Tom Matthews is willing to investigate it with her, but knows it is not writing. How does he know? He's been there. Tom remembers every one of his past lives and all the people who shared them with him. That is, until he meets Doctor Wright, someone he's never met before. His memory, whether Doctor Wright likes it or not, is the key to the new markings that have appeared on the Martian surface.
