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 the shop’s opening night. The chronology of the two series is entwined after that – if you want to read in the order of events, this would be your reading list:
You can read this series without reading Flatiron Five, and vice versa. You can read the two series in order separately, one after the other – I’d read Flatiron Five first in that case.
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.
There’s a Pinterest board for Secret Heart Ink, again with subsidiary boards for the individual stories.
