I consider myself a professional reviewer. Definitely not the best (Jamie Tivendale might as well take this title), and most certainly not the most experienced (eg Robin Carter), but a good reviewer nonetheless. And yet, for the first time in my life, I can't review a book I've read.
The book in question, as the title and the cover would suggest, is Blackwing by Ed McDonald. Why, would you ask, can't I review it? Because even if I tried, I couldn't possibly do it justice. Blackwing is one of the greatest fantasy books I've read in my life. Perfect in every possible way. Ed McDonald is on a par with Joe Abercrombie and Brandon Sanderson. Cast aside whatever you're reading and start Blackwing instead. That's all I have to say.
