I do like a book about a book shop.
This one throws in a small town, a new girl in town, and an age gap romance.
Both worry whether the other will think they are too young/old, boring/carefree, etc etc etc
Neither need to worry – they just need to get on with it.

Annoyingly when a book is part of a series I seem to be unable to resist reading the lot! And there were 5 of these. I read them whilst taking an extended journey involving 3 trains and 2 buses – the plot is easy to follow. A pleasant read.
