"When Works Progress Administration (WPA) editor Millie Lang finds herself on the wrong end of a potential political scandal, she's shipped off to Montana to work on the state's American Guide Series--travel books intended to put the nation's destitute writers to work.

But Millie begins to suspect that the answer might instead lie with the town's mysterious librarian, Alice Monroe. More than a decade earlier, Alice Monroe created the Boxcar Library in order to deliver books to isolated mining towns where men longed for entertainment and connection.
