Not really a book, but I very much liked the CDROM 'Aviation Meteorology' from Oxford Aviation Training.
There are two kinds of people: 'readers' and 'listeners'.
A reader can take a book and absorb whatever useful information it contains, a 'listener' falls asleep after a couple pages.
On the other hand a 'listener' will clearly remember any oral explanation in fine detail many years afterwards, while the reader will vaguely remember in which book to find the explanation.
I recently helped a 'listener' friend pass his written IR test, apart from me reading him the whole book, the only thing that worked is a CDROM with pictures and sound.
This CDROM is a miracle for 'listeners'.
