Christmas Press is delighted to announce that we have acquired world rights in The Secret of Panther Valley, a gripping mystery/adventure novel for middle-grade readers by talented author Brenton Cullen. The novel will be published in April/May 2027 under the Eagle Books imprint and was acquired via Debbie Golvan of Golvan Arts Management.
Christmas Press publishing director Sophie Masson said, ‘We are delighted to be publishing Brenton’s wonderfully pacy and intriguing novel, which richly conveys the atmosphere of the bush as well as being a fantastic adventure. With engaging characters, a deftly-woven mystery and a vividly-evoked setting, this is a novel that will have readers on the edge of their seats.’
While staying at his grandmother’s farm with his cousin Coby, mystery-loving 13-year-old Seamus learns the local legend of a panther stalking the region but his search for the truth turns to disaster when he finds himself alone, lost in a secret valley and hunted by a ruthless pair of men posing as documentary film-makers. He will need all his resolve, wits and courage to get out of the desperate situation he’s in, but in the process he uncovers a secret hidden for decades, and discovers a most unexpected and enigmatic ally…
Brenton Cullen explains the genesis of the novel: ‘The Secret of Panther Valley is an ode to the excitement of a country childhood and the secrets the Australian bush can hold. I grew up on farms that stretched for hundreds of acres, where I was always exploring the bush and creeks beyond our house and imagining adventures. I was fascinated by mysteries — especially the legend of the black panther said to roam the Blue Mountains. I often wondered what hidden creatures might be out there in the bush. When I was ten, I had a dream in which I was standing at our back door, watching in shock as a sleek panther crept past in front of me. That image has stayed with me. The Secret of Panther Valley grew from my adventures and that dream. I’m absolutely delighted that Eagle Books will be bringing this story to readers.’
Brenton Cullen is a fantastic new writer whose first middle-grade novel, The Prime Minister Problem, will be published by Riveted Press in April 2026. He has also written for magazines including Magpies and Books+Publishing, and was the recipient of the Ian Wilson Memorial Fellowship in 2023. We are delighted to welcome Brenton to the Eagle Books list!
