The Very Grumpy Boys Next Door - Love Next Door: Contemporary Reverse Harem Romance, #3

Small town girl from Mayhem Falls versus tall, dark, grumpy Bratva next door. Perfectionist, Tessa Newbury lives in a sleepy little town called Mayhem Falls, where everyone knows everyone else's business and she's never not planning the next town hall dance or best pie competition by the river. When the empty house next door to her is purchased by a trio of rather fascinating though grumpy men who instead flex their tattoos at her when she offers them her favorite lemon cake and her sweetest smile, she refuses to be perturbed and vows to win them over.
That is until she's secretly approached to spy on her new neighbors who actually belong to a very scary and infamous Bratva unit. Of course, she soon realizes no one snoops on the Bratva without dire heart-stopping, body-heating consequences.
