About a family of groundhogs - the first disappearance

I don't always work on the same project from one day to the next, and the holidays, which took me away from my computer, enforced a two-week stay in story development. However, upon returning to my groundhogs, and finding the hero sleeping in the sun while his sister was in the vegetable garden, I undertook to wake him up and give him a taste of what was in store for him and his family. He's such a lazy guy, and not particularly brave either. He has constantly to weigh safety and comfort against necessity - which sometimes takes the form of finding a way to avoid his mother's wrath. This is especially true when his elder sister comes up missing and the passage to the garden is blocked. Behind him, in the den, waits an angry, hungry mother with little patience for her ne'er-do-well son. Ahead lies the labor of digging a new garden door beyond which lie several unpleasant, even dangerous possibilities, but also the temptation of a richly growing vegetable garden, the solution to the gnawing emptiness in his belly. And what has happened to his sister? Will his mother accept him back without evidence of her whereabouts or information on her fate?
