Box-set and Invasion both on sale!

"Invasion" is available for pre-order for just 99p/99c and the box-set of books 1-3 is at a significant price-drop of £2.99/$3.99. You can get all four books right now for less than the cost of a coffee and a cake and they will last a lot longer.

Don't miss out. I won't be reducing the price of either of these again for a while.
