Assuming no cool dark delicious mountain pools are handy and it's too hot to sleep, when temperatures blister and everything swims, the only answer is to switch off, tune out, lie down in the translucent green shade of the grapevine and drift off on the imaginary breeze of a good book.
Somehow the remarkable stars of the books which carried me through the worst of last week - John Wray's South Sea Vagabonds and Barry Brickell: A Head of Steam by Christine Leov-Lealand - seemed to share a theme.
Johnny Wray's is an epic 1930s tale of building his first vessel, a sturdy 34-foot, cutter-rigged, beamy, kauri carvel Ngataki, to his own design from scrounged materials on his parents' Remuera front lawn, and sailing away.
Wray (1909-1986) writes in the witty, understated, self-deprecating style of the era, sans juicy biographical details, so readers can't know whether he was a convention-defying prodigy or not, whereas Leov-Lealand reveals Brickell displayed early promise by nearly burning down his parents' tinder dry, Devonport villa when he fired up a kiln under the floorboards as a child.
However, by the time they were young men, they were both clearly temperamentally unsuited to complying with their parents' hopes of proper jobs in carpeted offices.
