Following up on her international best seller The Zookeeper's Wife, Diane Ackerman tells the breathtaking story of the stroke that deprived her husband, Paul West - a distinguished novelist and poet - of every scrap of language beyond the syllable "mem". In her characteristically glorious prose, Ackerman weaves together the latest science on stroke and the brain’s ability to store and process language with her intensely personal journey as caregiver in helping Paul to an extraordinary recovery, and the impact of all this on their decades-long marriage.
