Crime & Thriller

Two small-town booksellers (and their cowardly dog) solve a decades-old murder mystery in this witty debut novel, full of literary clues, sparkling dialogue, and comedic insights into the world of bookshops.


"When we opened Sherlock Tomes, people warned us that we'd made a terrible mistake. People warned us that e-readers were taking over. People warned us that we'd never compete with Amazon. The one thing they didn't warn us about was the murders..."


Introducing...Β The Bookshop Detectives!


When a mystery parcel arrives at Sherlock Tomes bookshop in small-town Havelock North, New Zealand, husband-and-wife ownersΒ Garth and EloiseΒ (and their petrified pooch, Stevie) are drawn into the baffling case of a decades-old missing schoolgirl.


Intrigued by the puzzling, bookish clues, the two ex-cops are soon tangled in a web of crime, drugs, and floral decapitations, all while endeavouring to pull off the international celebrity book launch of the century.
With their beloved shop on the chopping block and the sinister suspect who forced them to run away from Blighty reemerging from the shadows, have Garth and Eloise Sherlock finally met their Moriarty?

Children & Young Adult

Enemies-to-lovers doesn't get more high stakes than a witch and a witch hunter falling in love in bestselling author Kristen Ciccarelli's latest romantic fantasy.


On the night Rune’s life changed forever, blood ran in the streets. Now, in the aftermath of a devastating revolution, witches have been diminished from powerful rulers to outcasts ruthlessly hunted due to their waning magic, and Rune must hide what she is.
Spending her days pretending to be nothing more than a vapid young socialite, Rune spends her nights as the Crimson Moth, a witch vigilante who rescues her kind from being purged. When a rescue goes wrong, she decides to throw the witch hunters off her scent and gain the intel she desperately needs by courting the handsome Gideon Sharpe – a notorious and unforgiving witch hunter loyal to the revolution – who she can't help but find herself falling for.
Gideon loathes the decadence and superficiality Rune represents, but when he learns the Crimson Moth has been using Rune’s merchant ships to smuggle renegade witches out of the republic, he inserts himself into her social circles by pretending to court her right back. He soon realises that beneath her beauty and shallow faΓ§ade, is someone fiercely intelligent and tender who feels like his perfect match. Except, what if she’s the very villain he’s been hunting?


The Crimson Moth is the thrilling start to a romantic fantasy duology where the only thing more treacherous than being a witch…is falling in love.

Biography & Memoir

What if we could redefine leadership? What if kindness came first?Β 


When Jacinda Ardern became Prime Minister at age 37, the world took notice. But it was her compassionate yet powerful response to the 2019 Christchurch mosque attacks, resulting in swift and sweeping gun control laws, that demonstrated her remarkable leadership. She guided her country through unprecedented challengesβ€”a volcanic eruption, a major biosecurity incursion, and a global pandemicβ€”while advancing visionary new policies to address climate change, reduce child poverty, and secure historic international trade deals. She did all this while juggling first-time motherhood in the public eye.


Ardern exemplifies a new kind of leadershipβ€”proving that leaders can be caring, empathetic, and effective. She has become a global icon, and now she is ready to share her story, from the struggles to the surprises, including for the first time the full details of her decision to step down during her sixth year as Prime Minister.


Through her personal experiences and reflections, Jacinda is a model for anyone who has ever doubted themselves, or has aspired to lead with compassion, conviction, and courage. A Different Kind of Power is more than a political memoir; it’s an insight into how it feels to lead, ultimately asking: What if you, too, are capable of more than you ever imagined?
