I presume this book was published to cash in on the popularity of Derry Girls. If you're interested in the Troubles I wouldn't recommend it, despite the covers claims, it's much more about 90's drinking culture and I did that and other people's stories about drinking Brerzers till they barf aren't interesting!
The structure of the book was also quite confusing as it frequently jumps around in time for the sake of a pointless anecdote.

I enjoyed the bits of the book about Alix's mum who would be a much better subject for a memoir or biography.
