My promises:

• I’ll never use your email address for any other reason than to keep you informed about The Merlin Spiral series of novels.
• I’ll never sell or give away your email address.
• I won’t email you very often.

Note that only the email address itself is required.  The other information just lets me know a bit about you.

The postal code is especially important if you want to be notified about any of my book signings in your area.
