I just finished The Philosophy of the catcher in the rye - super interesting, really enjoyed it.
Reading; Red Comment, Heather Clark - biography of Sylvia Plath. Thoroughly enjoying it, though "enjoying" feels like the wrong word due to the heavy topics it goes into.
Also reading Animorphs K.A Applegate. Nostalgic read and a nice, easy one to pick up when I need something less intense. Up to the 12th book!
And a couple of poetry books on the go; Beautiful Chaos - Robert Drake (eh, it's okay), All Dogs Are Good - Courtney Peppernell (fantastic! Will definitely read more of her stuff!) and Ariel - Sylvia Plath (a re-read as I know most of them already but interesting to read with the extra insight of the biography).
