Possibly, the book blurbs for Books 2, 3 and 4 don't really matter. After all, if you have been reading a series of books then it is the book before which will influence whether you read the next one. Even so, I want to write a blurb that could possibly hook new readers too. Here is my first attempt for the blurb for 'Out of Time.'
Eric and Ursula are recovering by the sea, but they know they cannot stay there.
For the time being they are safe, however the OSS continue to hunt them.
The children cannot hide forever and they want their lives back, but time is running out.
The final exciting installment of 'The Adventures of Eric and Ursula.'
