Another day, another parallel universe - sometimes it just seems too easy to hide a plot in a paradox.
On the whole, it was a good page-turner and not over-stuffed with nonsenses (something you can't say for every EDA). It's brutal, for sure, as much as any Doctor Who book I've read. The casual cruelty, the disregard for life and justice, the complete absence of compassion are all too real and happening in too many places in our own time, on our own planet, but it makes for an often uncomfortable read and the cliff-hanger ending would have been a nuisance if I didn't already have the next book ready to read.
So, a pleasing pot-boiler; not one of the best, certainly not one of the worst. Heavily centred in the plot rather than the characters and subsequently, an easy read, but be prepared for the casual horror which I found overwhelming at times.
