Worth the Wait by Shannon Davis

High school English teacher Claire Gibbs thought she’d found love but a broken heart was all she had to show for it. When her latest disappointment turns out to be a smooth-talking control freak, she swears off men. Although she couldn’t deny wanting the fairy tale—a happily ever after with Mr. Right—she was in no rush to date again.
Until she met Caleb.
Air Force officer Caleb Williams’ love life could be summed up in three words: crash and burn. All he wanted was to find a love that would stand the test of time. After a string of failed relationships with high maintenance drama queens, he gave up hope of finding someone special to share his life with and decided to fly solo.
But then he met Claire.
As fate keeps bringing them together, waiting for the right one might not take as long as they thought. Sparks ignite and passion flares as their dreams of finding true love become reality. But a possessive ex will stop at nothing to prevent their happily ever after. Will the one thing they’ve waited their whole lives for be destroyed at the hands of a killer?
