Nobody - not her kids, not her maths-genius husband - could have predicted that Lucy Crocker, former children's librarian and computer ignoramus, would save the family's computer software company with her fantastical Arthurian tale of knights, sorcerers, trolls. Now, her husband Ed wants her to write the sequel. The sooner the better. But Lucy is having trouble, and not just with the computer game. Ed is spending too much time with his punk publicity director Ingrid. Her sons are spending too much time with their computers. So - without stopping to tell Ed - Lucy dispatches her two computer-nerd sons to canoe camp and sets off for her family's north-country cottage and a rendezvous with a long-lost admirer. With potentially disastrous results for the entire family . . .
