I get this question all the time.
In the dedication in BAM!, I say:
“To Biruta, because my wife, Sara can’t bear to read my books because she lives it”
So who is Biruta? Years ago, I bought an antique watch at a tag sale and on the back it said. “To Jack, Love Biruta, 12/25/44″
I always wondered who Biruta and Jack were. Was Jack a soldier going off to war? Biruta will always be my other woman. The secret is out!
