The Eternal Bachelor by Lizzie Chantree

Demi is a vibrant and independent woman who seemingly has it all—a fulfilling job with her family, a long-term boyfriend, and a close-knit circle of friends. As her relationship with her boyfriend starts to crumble and her job with her family becomes precarious, Demi’s life begins to fall apart.
Enter Miles, her best friend since childhood, an eternal bachelor with an infectious zest for life. With his dark curls and sparkling green eyes, he has always been a constant in Demi’s life, a source of laughter, understanding, and unwavering support. Yet, behind his enigmatic smile lies a longing for something more. And that something is Demi — the one person he can’t have.
But as the seasons change and the bright hues of summer envelop Cherry Blossom Lane, Demi starts to see Miles in a different light. What was once friendly familiarity now blossoms into a heart-fluttering affection she never expected. The chemistry between her and Miles is undeniable, and the magnetic pull between them grows stronger with every stolen glance and lingering touch.
Caught between the ties to her past relationship and a charismatic playboy, Demi must confront her deepest fears and take a leap of faith. Will Demi and Miles find a way to be together despite the odds stacked against them? Or will fate conspire to keep them apart?
