Why Are There Alternate Titles?
If you're searching for these books online or in bookstores, you might run into some confusion. The novels were originally published under one set of titles (Lifelines, Warning Signs, Urgent Care, and Critical Condition) and later reissued or printed internationally with new names (Lifelines, Catalyst, Trauma, and Isolation). Rest assured, the stories inside are identical!
Can You Read the Books Out of Order?
Each book in the Angels of Mercy series shifts its primary focus to a different protagonist among the core group of women working at Pittsburgh's Angels of Mercy Medical Center. While each medical mystery is self-contained, the overarching relationships, personal struggles, and character growth develop sequentially from the first book to the fourth. For the best experience and to avoid spoilers regarding their personal lives, we highly recommend starting with Lifelines and proceeding in order.
