The Stepmother. The Stepmother Series, #1

Their connection flares hot in an instant.but is it doomed to fizzle out?After the death of her estranged father, Hayley McAllister plans to endure cold, wet England just long enough to tie up loose ends. Then she's heading straight back to Ibiza, where she lives exactly as she pleases-performing her music, soaking up sunshine, and indulging in flings with gorgeous women. She has no interest in meeting her dad's new wife.
A wife Hayley assumes must be just as bitter as he was. Until she comes face to face with Diane Astell-a walking, talking dream, from her dark hair and eyes and brilliant smile, down to her divine legs. Diane is intimately acquainted with heartbreak and loneliness, both within and outside of marriage. Now? She just wants to let it all go and have some fun for a change. Despite their age difference, she quickly recognises a kindred spirit in the beautiful, vivacious Hayley.
Their sexual chemistry is hotter than the Ibizan sun, but their undeniable connection comes with an expiration date-and consequences neither expected. Now, both must decide if holding onto lives they thought they wanted is worth losing the love of a lifetime for.
