At the heart of Michael Ignatieff's riveting novel about a woman's descent into Alzheimer's are the tangled threads of a Midwestern family, frayed by time and tragedy yet still connected - as much by pride, embarrassed love, and sibling rivalry as by the painful ties of family loyalty. More than a tale of isolated tragedy, Scar Tissue explores the bonds of memory, their configuartion in self-identity, and their relationship to love, loyalty, and death.
