Hold Your Breath is my first book by Katie Ruggle, but won't be my last. This book is well written. The characters are amazing and my favorite thing about the book. Lou and Callum's story is chock full of action, suspense, humor and steam. This book has it all! I enjoyed this book from cover to cover and look forward to my next book by Katie Ruggle. Hold Your Breath is book 1 in the Search And Rescue Series but can be read as a standalone. This is a complete book, not a cliff-hanger, but the story does continue in the next book I believe. Personally there's nothing I hate worse than cliff-hangers, and since I'm ok with the end of this book I call it a complete book.
