Around the blogosphere I could find a series of very interesting and attractive contests, with captivating prizes:
Solaris Books is offering the chance for one lucky winner to win a time machine (this is not a real working time machine! It is fragile, contains small parts, and is for ornamental use only). This was the very model featured on the splendid cover of Extraordinary Engines, an anthology of top-hole tales edited by that bounder Nick Gevers! Moreover, five runners up will each receive a copy of the aforementioned Steampunk anthology! You can find all the needed details for entering this very interesting competition by following this link.
Pat over at Pat's Fantasy Hotlist has two very attractive contests. At the first one the prize is a complete set of the new UK edition of Stephen R. Donaldson's scifi masterpiece, The Gap, which is comprised of "The Real Story", "Forbidden Knowledge", "A Dark and Hungry God Arises", "Chaos and Order" and "This Day All Gods Die".
The second contest has another interesting series as a prize, Michael Moorcock's Chronicles of the Last Emperor of Melniboné, comprised of "Elric: The Stealer of Souls", "Elric: To Rescue Tanelorn" and "Elric: The Sleeping Sorceress".
The members of Book Spot Central (the former Fantasy Book Spot) have the opportunity to win some interesting prizes. First two lucky winners, one grand prize winner and one second place winner, can win a copy of Archer and Armstrong: First Impressions, a recently released hardcover from VALIANT Entertainment collecting issues#0-6 of by Jim Shooter and the legendary Barry Windsor-Smith. But, the Grand Prize winner will win a copy of First Impressions and a limited X-O Manowar Lithograph.
On the second contest one lucky winner will receive a copy of the novel "Star Wars: Order 66" by Karen Traviss.
