Reviews for The Chemical Cocktail
‘another splendidly energetic thriller… Packed with fascinating science, thrills, shocks and relationships both touching and horrible, this is a terrific read.’
Literary Review
‘Fast-paced, roller-coaster ride… The action-packed storyline, just the right side of bonkers, roams from Lisbon to England to the steamy depths of the Brazilian jungle as Erskine lets her imagination rip to great effect.’
‘[Erskine] writes with flair and confidence, whether describing a heart-of-darkness journey downriver into the Brazilian jungle or the quiet of Lisbon’s British cemetery.’
Financial Times
‘Excellent… not only captivating and well written, but also extremely informative. Chemical engineering mingled with mystery and adventure. It’s a blast!’
The Chemical Engineer
‘With a real gift for storytelling, Erskine delivers an endgame that’s definitely not what you were anticipating… our heroine Jaq is refreshingly female in a male dominated world… The Chemical Cocktail is an action-packed adventure perfect for any thriller-lover ready for a modern heroine to blow their socks off.’

I swam 24km in 5 days. Hard work?
Try tuna canning, salt drying or sulphur mining…

Delighted to celebrate International Week of Happiness at Work with a 99p deal in UK. Jaq Silver has found the perfect job in Brazil. Or has she?
The Chemical Cocktail (Jaq Silver Thriller) eBook : Erskine, Fiona: : Kindle Store https://www.amazon.co.uk/Chemical-Cocktail-Silver-Thrillers-Book-ebook/dp/B0FG8X59MT
The Chemical Cocktail goes right back to Jaq’s childhood and can be read first - only £0.99
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

🚨PUBLICATION DAY🚨
Ravenglass is available everywhere now! A tender and powerful tale of a gender fluid character trying to make their way in the 1700s, we can't recommend this incredible adventure novel enough 🏳️🌈
Order yours here: https://share.google/bfWyYAWWNBHLr9rB6
I was today years old when I learned I’ve been eating my favourite biscuits all wrong
Chocolate digestives: How do you eat them? Choc side up or down? - CBBC Newsround https://www.bbc.com/newsround/articles/cvg7lnp19n0o
Last of the first editions - snap them up quick - a unique investment!

Look who I found in @blackwelloxford when I was there at the weekend?
Not one but two of @erskine_fiona's excellent Jaq Silver thrillers #thechemicalcode and #thechemicalcocktail just along the shelves from The Cure.
Nice facing, Fiona! You'll have to come to Oxford to sign them!
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.

Greetings to all my friends at @bloodyscotland! So sorry I won’t be there this year but research takes priority @SwimTrek
First book of my holiday complete. Thank you @erskine_fiona. An entertaining & complex story - easily transporting me from the Maltese sun I’m currently basking in to the cold dark Teeside winter. I look forward to reading more about DI Julie Cadell.
Late to the party but absolutely loving @geowriter #nightclimbing
