Lust Hate Love by Ella Frank

As the sexy, charismatic bassist for world-famous rock band Fallen Angel, whatever Killian Michaels wants, Killian Michaels gets.
Or at least that was the case until the band’s gorgeous new manager, Levi Walker, shot him down after a blistering first kiss.
For Levi, managing these five guys is the opportunity of a lifetime, and he’s not about to let a case of sexual desire get in his way. He’s efficient, professional, and plays by the book. But tension simmers beneath Levi’s cool exterior every time Killian’s near, and soon enough the passion boils over, consuming them both.
As the Corruption tour takes them from country to country, a heated game of cat and mouse ensues. Levi tries to deny the irresistible pull of Killian’s seductive nature, but with an attraction as strong as theirs, it’s only a matter of time before the lust-filled hate turns to love.
