Sweltering heat, humidity so high the windows in air-conditioned buildings get steamed up. Not so in the bookstore. It faces northeast so doesn’t get much direct sunlight and didn’t get above 80 in the sstore today. The air conditioner doesn’t work so well but a good fan keeps the air moving and it was bearable. When it’s hot outside, what’s cool to read? Harry Potter and a lot of teen sci-if and fantasy — the Fablehaven series, Clement’s series, the Uglies, Pretties, Specials, Extra series are popular right now.
