About Me


I was born in in Liverpool, England and started my writing career as trainee reporter at the Liverpool Echo, where I worked until I was appointed Editor of the Liverpool Daily Post.  I wrote first book, Bridesmaids, while on maternity leave, under the pseudonym Jane Costello. 


My nine subsequent novels were all best-sellers in the UK, but after a decade of writing romantic comedies, I came up with the idea for YOU ME EVERYTHING and knew it would be different from anything I'd written before.  It was my agent who suggested I should abandon my pseudonym and change my name to Catherine Isaac but don't mind admitting that, after building up a lovely, loyal following the idea gave me a few sleepless nights.

In the event YOU ME EVERYTHING became by far my biggest writing success to date: it's been translated into 24 languages, won the Popular Romantic Fiction award at the RoNAs and a movie is in development by Lionsgate and Temple Hill. My next book, MESSY, WONDERFUL US will be published in the UK in paperback in March 2020. 

I still live in Liverpool with my husband Mark, my three sons and dog Maisie. As well as my writing, I also love running, walking in the Lake District and baking cakes (of variable quality). I love hearing from anyone who's read my books, so please do write an Amazon or Goodreads review if you're so inclined - or get in touch with me direct, on Twitter, Facebook, or Instagram.
