Summer is here and Zed contributors are fully immersed. In this roundup, we set out with Dan Rubinstein on his paddleboard adventure and dive into Robert Macfarlane’s treatise on the rights of rivers. Edward St. Aubyn – of Patrick Melrose fame – is back with a witty new novel and one reviewer says S.A. Cosby’s latest is his best. And for all you aspiring writers out there, you’ll want to wade into agent Kate McKean’s guide to publishing.
