Dr Toby Harper was exhausted when the police brought in the old man who’d been found confused and wandering, naked, through the nearby streets. Springer Hospital where Toby spent her nights working the ER was generally quiet at that time of night, but the disoriented man was thrashing and jerking, delirious and completely out of it. And when he vanished from the hospital not long after admission, Toby was hit with resounding guilt.When Toby’s attention was drawn to another elderly patient a few days later, her niggling concern that his symptoms were similar to the disappearing gentleman were met with disbelief. Especially from his own physician. But it was on his death that the horrifying diagnosis was made. Toby was fearful of an epidemic – but she couldn’t convince any of her peers. She knew there was something strange going on. But when murder found its way to the parking bay of the ER, and Toby had trouble at home, she knew she had to find answers – fast. Before it was way too late…Life Support by Tess Gerritsen is another gripping medical thriller from this author. I haven’t read anything of hers for awhile and I always forget just how GOOD she is at weaving the intricacies of the plot. Fast paced and intensely chilling, Life Support is one I highly recommend.
