What readers are saying about the Michael Flint thrillers:

“Fabulous book. Could not put it down!” 

“Great fast-paced novel! Has ALL the requirements to keep me seated and reading. Not an easy task! Very well written. An excellent read!” 

“The best I have read this year!” 

“Flint is today's James Bond, and I can't wait to see where his adventures will take him next!” 

“The characters are so real and the story line keeps you in suspense.” 

“Outstanding new characters. Intriguing plots that kept me totally involved. Loved Flint and looking forward to more novels involving him and his cohorts. Whole new arena for Diane Capri. Kept me up late at night not wanting to put it down. Recommended!”

“In my little world of mysteries and thrillers, what gives me the greatest joy? Easy: Characters I enjoy reading about and - be still my heart - discovering that I'll be able to read about them again and again as part of a series. So color me delighted to find this book, which introduces "heir hunter" Michael Flint.” 

“Flint strikes sparks – then fire! The action comes fast and furious. There's great procedural/forensic detail and engaging looks at each character with very well executed and exciting twists and turns, enough to keep things in suspense right up until the final page. Diane has not only given us a truly fascinating novel, she's laid the foundation for an epic new franchise populated with truly memorable characters.” 

“What a terrific story! I love side-by-side stories since it is so fascinating when they finally coincide in a dynamic conclusion.” 

“What a great fast-paced story which has the reader looking forward to the next line, paragraph and page as it's an outstanding page turner!” 

“Great new heir hunter! Flint is back!!! Heir hunter extraordinaire, Michael Flint, is back with his newest case!” 

“I was enthralled with this book because of the genealogist theme. I dabble in genealogy, and have hit my fair share of brick walls. Michael Flint is a great character, fully developed personality, with knowledge and fearlessness to pursue wrong-doing and try to make it right, not necessarily within the law. I couldn't put down either of the books in this series and am hopeful for more.” 

“I started reading Ms Capri's Jack Reacher spin-offs. I've read them all. Moving on to her other works. Great reads. Can't wait for the next in the Michael Flint series.” 

“I like the fast pace and not having to wade through a description of the mosaic tile walls in the lobby of some building. A tenacious character with a set of values and a conscience. A very good read. Couldn't put it down!” 

“Tense and captivating page turner. I really enjoyed the Heir Hunter series and am hoping for more real soon. Michael Flint is a true adventure hero every bit as good as Indiana Jones with a dose of Jack Reacher thrown in for good measure. He's highly principled, while somewhat flawed, but very loyal with a vulnerable side he'd rather keep hidden. Please Diane Capri......more, more, more!”
