Book 7

I've started writing Book 7. It will be a pivotal book as the government has assumed control over Beatrice's time travel program. Consequently, the K2 telephone booth will be replaced by a state-of-the-art time travel chamber, a chamber that may allow more chrononauts to travel simultaneously.
Where do you think the Canadian government will send the chrononauts? How could knowledge from the past help with today's national concerns?
