Author J.J. Green brings us Jas Harrington's next adventure. Jas and her crew jump to Mars to do two things. One is to find out if the Tansgalactic council has sent an information packet for them. Two to find out if the Shadows have infiltrated the planet. But along the way Jas meet's the doctor of her old ship who has been turned from experimenter into a lab rat for the species that Jas found on the planet that they had crashed on months ago. This is a great book and I look forward to reading the last two books in this series. I highly recommend this series too.
