The Portal

William and his brother Daniel come home from school one day to find their parents have disappeared - It's the first of a series of shocks they have to cope with, not the least of which is finding that their house has been built over an inter-stellar portal - It's some time before they can solve the mystery of where their parents have gone and why - and in the meantime they have to cope with visiting aliens, chickens, and making their own lunch - It's not easy - Not easy at all.
