When we started working on our most recent novel, Mayan Interface, we visited the Mexican Yucatan Peninsula, talked with people there, and took lots of pictures. At right is the huge stone arch at Kabah, a monumental gateway to the past — much like the one that Lydia gazes at and wonders, “Where will this gateway lead me?”

We also read every authoritative book we could get our hands on and attended a workshop on glyphs. In our story, four roughly-carved glyphs hold the key to a mysterious and deadly reality. Can Lydia translate the strange symbols fast enough to prevent more deaths — including her own?
