Secret Heart Ink is a series of contemporary romance novellas and a spin-off series from Flatiron Five. Each month, on the full moon, Chynna does a special tattoo that brings true love to the recipient. Secret Heart Ink tells the stories of those characters and their HEA’s.
In terms of timeline, Snowbound happens after In the Midnight Hour: in Damon’s book, Chynna’s tattoo shop is under construction. Snowbound begins during its opening night. You can read this series without reading Flatiron Five, and vice versa.
Secret Heart Ink also introduces three women from Honey Hill, Maine. They’ve been best friends forever and have a girls’ weekend in Manhattan to celebrate Olivia getting her doctorate. Liv is the science nerd. Lexi is the party-girl. Reyna is the cupcake queen. They’re three smart, fun women and I think you’ll enjoy their stories. I’m also pretty sure we’ll see more of Honey Hill in future.
There’s a Pinterest board for Secret Heart Ink, again with subsidiary boards for the individual stories.
