A Ripple of Pages and Secrets by Mona Archer

A Sorcery of Thorns meets The Starless Sea in this romantasy about a human girl who gets trapped in a magical and dangerous library world together with its brooding fae guardian.

Magical books and libraries are dangerous.
But even more dangerous are their warrior guardians, as Aline soon finds out. This guardian going by the name Roane is a handsome and grumpy fae male , and he’s about to become the bane of Aline’s existence.
That’s what you get when you get trapped inside the wondrous and perilous Library of Areon…

When Aline enters the magical Library of Areon to deliver a magical book, she can’t imagine she’d become trapped there, together with Roane, the brooding, dashing fae guardian, and his animal companions.
Roane wants her gone at any cost, and she isn’t excited at the prospect of remaining inside the giant cave full of monsters, either, but getting out is… complicated. If not downright impossible.
As impossible as the grumpy fae guarding it.
But in the mythical library world, things are not what they seem, and as for Aline herself… she may be something else. Something more.
Human? Ostensibly so.
Magical? Also.
Doomed? Well… that remains to be seen.
As Areon’s world starts to collapse and her feelings for Roane grow, she will have to decide whether she really wants to leave, or stay and fight for her newfound family.
