Penny Hartwell's dreams of being a celebrated artist have been reduced to sketching between shifts at a Boston gas station. Rent is overdue, inspiration has dried up, and her once-bright future feels like it's slipping further out of reach. Anthea Corey has spent centuries guiding artists to greatness, but after too many betrayals she vanished from the world. Now, reluctantly back from a decade-long retreat, this weary muse is determined to keep things simple--and her heart well-guarded. Neither expects to collide in the hushed halls of the Boston Public Library on a bitter winter's day. But when Penny and Anthea meet, something stirs--something neither talent nor time can deny. For Penny, it's the return of inspiration. For Anthea, it's the dangerous pull of hope.

And for both, it could be the beginning of something that blurs the line between art and love.
