Coming Down (Love in London #1)
Carrie Elks

Niall is an up-and-coming artist, recently returned from success in America. Volunteering to teach in an inner-city drug clinic, the last person he expects to see is the girl who broke his heart nine years earlier. Working closely together allows their old wounds to heal, forging a deeper connection between them. One that slowly starts to burn.
As she becomes tangled up with a neglected child and her drug-addict mother, Beth finds herself drawn to Niall. But neither of them can anticipate how hard it is to tread the thin line between friendship and desire.
