adding books to a series

[Mia]

Hi,
I have a few books that need to be added to various series of mine. Can anyone help me? Here's a list of the book(s) and which series it should be added to on my page:

Sleeping with the Sandman -- Surprise Passion Series
Surprise Passion Box Set -- Surprise Passion Series
Keeping Up -- Hollywood Hotties Series

Thank you.
