True Colors by Clare London
From the very first, Zeke Roswell and Miles Winter are like oil and water. After a tragic fire claimed his brother's life, Zeke's personal and professional life spiraled out of control, and now he has no choice but to sell his gallery to cover his debts. Enter successful entrepreneur Miles, who buys it and plans to make a commercial success out of Zeke's failure.
Their initial hostility stands no chance against the strong passion that ambushes them. Zeke's talent and lust for life intoxicate Miles, and Zeke finds Miles' self-assurance and determination equally fascinating. But it's not until an unsolved mystery of violence and stolen sketches threatens to sabotage any chance at happiness that Miles and Zeke realize they have a chance at all.
