Too Much to Handle is a free read that was serialized on the Harlequin website and part of the Bluff City series (though it, and all books in the series, can stand alone).
Blurb: For fourteen years, Henry Peterson has lived in the shadow of guilt. Ever since his friend Ken’s death, he’s never let anyone get too close. But when Ellen Simms moves in next door, determined to make peace with the past, suddenly keeping his distance is no longer an option. Ellen is the last woman Henry should want. Not only is she Ken’s sister, her parents never forgave him for what happened to their son. Now that she’s back in Bluff City, vibrant and quirky and all too irresistible, Henry finally realizes he deserves something good.
