Bitter (Taste of Love #2)

France. Céleste Elliot finally returned to the place she considered home, heading up the Paris office at a dream company; a job she worked hard to get. While many memories of the past haunt her daily and she struggles to connect with her family, she thrives at work, taking charge of everything around her, leaving no room for errant emotions.
Until he shows back up in her life.
Not only is he invited to her best friend, Saoirse’s, wedding, he’s been sent to work in her office for months. As Céleste demands boundaries, Theo is ready to chip away at the walls she’s constructed one brick at a time.

Theo Grant always knew Céleste was the one who got away. He couldn’t understand why she’d left without a word when they were just kids. His favorite dance partner, his best friend, gone.
An opportunity to leave England—even just for a short time—and work in the Paris office she leads gives him just the opening he needs to win her back.
Except, she was never really his. Refusing to squander his one chance to finally be with his true love, Theo puts his heart on the line, shares his own shocking secrets, and diligently stands with Céleste through every heartbreaking discovery unfolding from her childhood.
Is Paris really the city of love, the city for second chances? Theo knows it is and will stop at nothing to show Céleste how little their time apart matters, so long as they have each other.

Bitter is a standalone novel with a HEA, but will have more depth if read in series.
