Here's what people are saying about Katie's books...
Well written story and well developed characters! I was engrossed from the very beginning to the last word! Loved it! 5 stars!
- Amazon Kindle Customer
This book hit all the marks for me: a heroine who pursues her passion, a hero who's willing to take risks for love, and a storyline I found intriguing...5 stars for another winner from one of my favorite writers.
- Peggy Jaeger, award winning author
Ghost in the Machine is a gripping paranormal thriller I couldn't put down... Katie O'Sullivan grabs the reader by the lapels and doesn't let go until the last page. I love a good paranormal thriller but this one took me by surprise... if you're looking for romantic suspense with paranormal elements, you're going to love Ghost in the Machine. Highly recommend! 5+ stars
- N.N. Light Book Heaven reviews, Amazon Vine Voice reviewer
While Son of a Mermaid has strong romantic features, there's just as much adventure - think Game of Thrones underwater without the graphic sex... O'Sullivan does a masterful job creating a believable underwater culture. She also writes with complete authenticity about life in a seasonal coastal town.

If you loved A Star is Born, you will LOVE this emotional rockstar redemption story (Quinn's Resolution)
- 5 star review from Angie, Amazon Vine Voice reviewer
O'Sullivan sets her books (yes, I eagerly pre-order each new release) in Cape Cod. I've never been there except through this talented author's words. This fun, fast-paced story really satisfied! Highly recommend!
