These Hollow Vows (2021) is the first installment in a young adult faerie romantasy series by American author Lexi Ryan. Ryan was previously known for writing contemporary romances for adults (in various subgenres); These Hollow Vows is her first novel for young adults. It was nominated as a Readers’ Favorite Young Adult Fantasy and Science Fiction novel in Goodreads’ 2021 Reader’s Choice Awards and has been compared to other young adult fantasy romances like Tricia Levenseller’s The Shadows Between Us.

Ryan subsequently published two other installments in the series. These Twisted Bonds (2022) continues Brie’s narrative as she manages her life in Faerie in the aftermath of being betrayed by Sebastian and Finn. Ryan has a second duology set in the same universe as the first two installments, which are loosely connected to the narrative from the first two books but not directly informed by one another. Beneath These Cursed Stars (2024) follows Brie’s younger sister, Jas, as she seeks to battle a reincarnated Mordeus. The second book in this duology, Between These Broken Hearts, is scheduled for a 2025 release.

These Hollow Vows was well received by readers, who praised the novel for its fast-paced plot, exciting twists and turns, and engaging love triangle.
