Willow......the kid is home and wants to move to Costa Rica!  She brought
home a "nut" her host family little sisters gave her.  It is about 1 inche
across and about 1/2 inch thick, square shaped and has lighter color around
the edge with a dark line throught the cener of this.   Pretty much looks
like a "burger bun"........any clue?  In was in a bag of shells the children
collected and left on her bed.....so might be from beach area.
I ordered you book from your sister, so dying to see it!  Sincerely, Nancy C.
