Gold Babies and the Brothers Muldoon:
UK Kindle NB 49p though supposed to be free
Midnight. Valkyrie Cain approaches an old, ramshackle church to make a delicate deal with a trio of ugly, hairy goblins. To her absolute non-surprise, the goblins have no intention of honouring that deal- but not to worry. Skulduggery Pleasant is standing by to deliver a surprise of their own. Things, however, don’t go exactly according to plan. Not least because the goblins have a sister. A very big, very strong sister. Who might just have a TINY crush on one of our heroes…
The Lost Art of World Domination
A shot of Skulduggery action for free. It isn’t easy to take over the world. First you need the scheme. Then you need the muscle. Then you need to come up with a system for ruling six billion people and keeping them from revolting. It takes a certain kind of man to take over the world. Scaramouch Van Dreg, however, is not that man. But he has one thing going for him. He has his arch enemy, Skulduggery Pleasant, chained up in his dungeon, and the only person who is coming to save him is the skeleton detective’s 13 year old sidekick. What could possibly go wrong?
