Let me start of by saying, "What a fantastic book."
The plot follows Batman as he tries to solve the mystery of the identity of "Holiday", a serial killer striking on public, you guessed it, holidays.
This is a story of the early years of Batman and done very much in the style of "Batman: Year One" although knowledge of this title, or indeed any Batman continuity, is not required. The writing is superb as it follows a positively Machiavellian plot, with twists and turns whenever you least expect them. This one will keep you guessing to the very end - and even then questions remain.
The art, whilst not breathtaking, services the book very well as an overly detailed or coloured approach would not be in keeping with the story being told.
Next to the seminal Dark Knight Returns, this is the best Batman tale I have read to date, largely due to the fact it is so different in pace and content to the more traditional Dark Knight stories.
If you're a big Batman fan, or just love a good mystery, add a star to the five given as you really cannot afford to miss this!!
