Reviews for The Chemical Detective

‘Fiona Erskine is an engineer, and in Jaq Silver, who shares her profession, she has created a wonderful antidote to all the resentful, floppy victims of much domestic noir… Her adventures are eye-popping and exciting.’

Literary Review

An audacious, female-led thriller which took the disposable women of the James Bond franchise and flipped the concept entirely on its head

Chemistry World Book Club

‘Action, intrigue and a stonkingly modern heroine. It’s a blast.’

Sunday Times Crime Club

‘Just the right blend of suspense and tension… I recommend this original and compelling debut novel for fans of mysteries and thrillers, as well as for those looking for a credible female protagonist in a genre dominated by male superheroes. Already, I am looking forward to reading the next instalment in this series.’

Forbes

‘Imagine the love child of Jack Reacher and Nancy Drew…a delicious cocktail of dating and detonations. Call it Mills and Boom.’

Trust me, you won’t regret reading this. Exquisite prose and a rollicking, propulsive, deeply moving story. @novelcarolyn is a fearless writer who wears her deep research so lightly that you are instantly immersed into the booming north of the 1720s

Ravenglass by @novelcarolyn is the most beautifully written exploration of how we once lived and worked and lived and loved and fought in the north. A cracking good read, I cannot recommend it strongly enough - a complete breath of fresh air.
