All is not what it seems in this gripping novel about two sisters' lives: one who leaves her secular Catholic life to become a nun in deepest Africa, and her sister who goes to search for her when she goes missing.

Elodie O'Shea abandons her children to her estranged husband to go on the search for her sister, Bridie. What she uncovers reveals as much about herself, her marriage and her family than her missing sibling.

Sister Sebastian's Library is a deeply moving exploration of relationships, loyalty and trust. With quiet confidence and perfectly pitched prose, Phil Whitaker challenges our understanding of the essentials that make us human.
