On 12th September 2015, a 30-ton humpback whale breached and landed on Tom Mustill and his friend Charlotte Kinloch as they paddled a sea kayak in Monterey Bay, California. Incredibly, both survived the incident, but the near-death experience haunted documentary maker Tom and left him wondering if the whale was deliberately trying to hurt them. To find the answer, Tom returned to California in 2018 to investigate. Tom meets those who have survived similar hair-raising encounters and the experts who know the whales best. What he discovers raises far bigger questions, not just about what happened that day but also about our relationship with whales and their future alongside us.

Stunningly diverse, plants have served us in many critical ways, from providing food, shelter and clothing to life-saving medicine. And yet we know very little about them. A luscious exploration of the natural world, Smarty Plants effortlessly integrates pioneering science with a light hearted look at how plants behave, revealing a world where plants are as busy, responsive and complex as we are. From the stunning heights of Utah's Great Basin Desert to the rainforests of Canada's west coast, Smarty Plants follows lead scientist and ecologist JC Cahill as he treks the green world and discovers that plants are a lot more like animals than we ever imagined.
