Funny...she gave me Dr Seuss' Many Colored Days to celebrate us finishing our first year together.
I have a pen thing too and once bought my MIL a $150 fountain pen and a notebook of handmade paper when she said she wanted to write a book about their family. Mr. Lil wanted to skin me alive
I'll definitely find her a book...oooooooooo maybe I can look for a signed children's book by someone I know she loves. When we went to a conference she and I had fun getting our books signed by the authors.
