In Anne Charnock’s Bridge 108 (47North, RRP£19.99), 12-year-old Caleb embarks on a perilous migration from drought-ridden Spain to the UK. Once on British shores, he spends the next few years labouring in the shadow economy to avoid the attention of the authorities, working at a market stall, a vineyard and a fishery. There’s no shortage of adults willing to exploit him and abuse his trust. The novel’s near-future setting feels grimy, sweltering and lived-in. Environmental collapse has brought out the worst in everyone, and instances of kindness are few and far between.
