Am new to Adult ( and YA) Romance books - only started reading them last year,but I highly recommend :
The Ex Hex (Ex Hex #1) by Erin Sterling
And the sequel :
The Kiss Curse
(Ex Hex #2) by Erin Sterling
All the characters are whole ass people who feel like they exist outside the confines of the story.
Their reactions , interactions and motivations make sense
The world building is subtle yet intriguing
The writing is really good !
