I checked the biggest online book store of Holland, and they offer two different paperback versions. Shipping costs will be higher though..
Thanks, I was able to find Moon Over Soho on abebooks through the book depository, I’m pretty sure it’s the format I’ve been looking for (published by orion, about 7.7 inches tall. I know, how picky can I get?!).
Now just to find Whispers Under Ground!
