Bombshell by Calliope Stewart

“A halfling witch, a lonely Cthulhu, and the tattoo parlor that brought them together.”

Dallan
For over three hundred and fifty years Dallan Elder has lived his life the way he wanted to, and as one of the last remaining members of the Cthulhu race, he’s is also used to being alone.
That was, at least, until he found Port Haven and the family that came with it. Now as the owner of Monstrous Ink, he works to protect that family everyday, a family that includes the beautiful green-eyed halfling Effie Finch.
Dallan wants nothing more than to claim completely as his, but hasn’t been able to get past her tough exterior and the business-with-benefits box she’s firmly placed him in. So, for almost fifty years he’s made himself content with what they have, figuring he’d have a long time to convince her to be with him. Then Effie’s past rears its ugly head and Dallan is faced with possibly losing her forever.

Effie
Born as the halfling daughter of a tree nymph and a warlock, Euphemia “Effie” Finch has always straddled two worlds and was never enough for either side. Finally she broke away, and in doing so, she met them: the monsters that worked at Monstrous Ink.
Now, years later, she works as their in-house witch, spending her days enchanting and, uh, collecting ink from the shop owner Dallan. Effie insists their time together is strictly business, afraid to get too close to how she really feels for fear of never being enough for him either.
But when Effie’s closest friend is put in danger, she will have to turn to the one place she vowed to never return to in order to help them.
