Rollback: Robert J Sawyer – Book

Description

Dr. Sarah Halifax decoded the first-ever radio transmission received from aliens. Now, some Thirty-eight years later, another message is received and Sarah, now in her twilight years, may hold the key to deciphering this one, too… if she can survive long enough.  A wealthy industrialist offers to pay for Sarah to have a rollback—a highly expensive experimental regeneration procedure in order to try and get Sarah to do again what she’d done once before: figure out what a signal from the stars contains.
