Kissed by an Angel by Elizabeth Chandler

Ivy is a sweet, innocent teenage girl who loves hanging out with her two best friends Beth and Suzanne, has a great job at the mall working for two addled old ladies, and is trying to adjust to life living with her stepbrother Gregory and stepdad Andrew in their mansion after living in an apartment for her entire life. And then there's Tristan. He's everything she could have asked for in a boy. He's kind, sensitive, thoughtful, understanding, and he's even nice to her little brother, Philip. And he's on the swim team and helps her get over her lifelong fear of water. They are absolutely happy- until Tristan is killed in a terrible car accident. Now he's an angel, and his job is to protect Ivy from the person who killed him, which turns out to be harder than he thought. Can he save her, even when he knows saving her will mean letting go? I definitely rate this book 5 stars.
