"Vital Signs" is a novel that takes us deep inside a marriage in crisis, teasing out the unspoken rules that run - or ruin - love relationships. So much is taken for granted in a long marriage, so much is relied upon, so much is resented, so much is never spoken. But when Anna, Mike's beautiful and self-possessed wife, begins to mangle her sentences as a result of a brain aneurysm that could kill her at any moment, it's as if Mike has woken from a long dream in which he was only thinking about himself. Or is he still only thinking about himself? In his panic to show his wife that she has been his entire universe, will he finally confess all the ways in which he rebelled against her power over him, the way he betrayed her? Incoherent with guilt, he uses his talent as a graphic artist to draw his way closer to his wife, trying to communicate with her, and himself too, through signs and symbols. Mike is deeply flawed, hovering on the knife-edge of a confession, selfishly looking to the woman he loves for absolution even as she faces the possibility of her own death. And through this portrait of a marriage in crisis, Tessa McWatt leads us deftly and deeply into the workings of a relationship that blooms and withers and reblooms over time, and into the lies and the truths necessary to sustain it.
