EILEEN WILKS is a fifth-generation Texan. Her great-great-grandmother came to Texas in a covered wagon shortly after the end of the Civil War-excuse us, the War Between the States. But she's not a full-blooded Texan. Right after another war, her Texan father fell for a Yankee woman. This obviously mismatched pair proceeded to travel to nine cities in three countries in the first twenty years of their marriage, raising two kids and innumerable dogs and cats along the way. For the next twenty years they stayed put, back home in Texas again-and still together. Eileen figures her professional career matches her nomadic upbringing, since she's tried everything from drafting to a brief stint as a ranch hand-raising two children and any number of cats and dogs along the way. Not until she started writing did she "stay put," because that's when she knew she'd come home. Readers can write to her at P.O. Box 4612, Midland, TX 79704-4612.
