"A witty, globally-scoped expose of corporate greed and environmentalism told through an absorbing character-rich tale" -- Joanne Owen, Love Reading UK; "A caustic novel for our times about corporate greed, the hubris of bankers, contradictions of the clean energy economy, and their unintended consequences on everyday people. This is a hugely entertaining and enlightening look at the banking world post-2007." -- Book Riot: EXCELLENT...BOOKS OUT IN THE UK; "After reading a lot of claustrophobic, navel-gazing books, it is refreshing to pick up The Umbrella Men -- Rich, immersive novel of the type that really isn't seen much these days...what makes this book so readable and likeable are the well formed characters whose lives are disrupted personally and professionally by machinations of those in power. -- Netgalley reviewer; "A highly entertaining romp that very accurately portrays the conflicting objectives and modus operandi of groups of investment bankers, hedgies, environmentalists and a small rare earth mining company as they each try to maximise their own positions, and with abundant human frailties on show." -- Waterstones reviewer
