Wow. I could not put this down. Dark, gripping, unpredictable - what a start to a series! Apart from Nalini Singh's 'Guild Hunter' series, I've yet to come across an angel book that I've really enjoyed. Well, I thoroughly enjoyed this one! 
 Our heroine, Penryn, goes off in search for her sister after she is abducted by angels. Angels which, six weeks earlier, had demolished the modern world. She teams up with Raffe, another angel, due to their similar goals. 
 What was refreshing is that she didn't spend the book swooning over Raffe. Or angels in general. Penryn, a great character with more than just end-of-world struggles, the twisting plot (my favourite kind) and the setting made for great reading. Some parts of it were quite strange but I suppose it is the apocalypse. 
 There are still questions unanswered as we don't know why they invaded or much about the angels in general, in particular the different "sides" and internal politics. I'm looking forward to finding all this out in the sequel. I didn't want it to end and that hasn't happened with a book since I read 'Hunt the Moon'.
