This book is absolutely unhinged, and I loved it.  Formerly a nurse on the run, Margo is a new woman upon settling in a small town as an “experienced” librarian.  Two years in, and still no one knows about her past until Margo lets something slip to Patricia, her new coworker.  The dual narrators become fast frenemies, equally obsessed with their exploits—Patricia secretly writing her next novel about Margo, and Margo “helping” people under the guise of a warm yet no-nonsense librarian.  Fact and fiction blur into one in this darkly funny tale of two driven women.
