Iris Nightingale is more than okay. She has her life planned out to a perfect schedule. Work, run, sleep, repeat. She spends her quiet Friday nights sitting alone on a bench in the park, trying to push back the memories that no amount of running can help her escape.

But one evening, there’s someone else on her bench - Hunter. Tall, wry and infuriating: everything about him gets under Iris’s skin. Little does she know that he's about to upset more than just her routines...

Hired as a consultant at the firm where Iris works as engineering manager, Hunter has a knack for knowing just what to say to irritate her, and Iris can’t help rising to the spark in his eyes each time.

Sent away on a work trip together, Iris is taken out of her comfort zone. As their connection deepens, will Iris finally be able to face the memories that have been haunting her for years? Can her blossoming relationship with Hunter survive some brutal truths?

Only one thing is certain: The spark between them is beyond Iris’s expertise, and there's no running away from it.
