Her Captive Dragon by Marianne Morea

A dragon shifter, a curse, a rare book, and the woman who is the key to setting him free…
Finding real love doesn’t happen between the dusty pages of old books. Not usually. But nothing is usual for antique folio researcher, Hannah Foster, when a chance meeting with an old beggar woman changes everything in her quiet librarian’s life.
A simple thank you for a simple kindness would have been enough, but when the old woman’s prize possession opens Hannah to a fantasy world she’s only known in books, she’s in for the adventure of a lifetime. A fantasy hero in the flesh. Talk about a book boyfriend come to life! His story tests both the laws of physics and her imagination, but in her heart she knows it’s true. Now it’s up to her to help him break his captive curse and earn their own happily ever after.
