Apologies- I completely missed chipping in toward books for you. (Building 19 didn't have what you wanted and I haven't been to another bookstore since. Moving so that I no longer go past Borders on the way home from work has significantly decreased my book browsing.) I was thinking of when schools get out up here, and assuming you wouldn't need them until mid-June. Is the DC school year significantly different, or do they stop the mentoring program a month short?
