Jack Benson and Hal Hastings arrive in Dunhaven, looking for adventure. But in a sleepy, little town, they might not find much. When they find out that there is a submarine in the shipyard, they decide that this is what they have been looking for.

The torpedo submarine's inventor, Jack Farnum, is looking for investors to help him kick his new shipyard into high gear. He already has his crew set, with sixteen year old Jack Benson as the captain, and his friend Hal Hastings running the engines. But, there may be some changes to the crew of the Pollard on the horizon.

Captain Jack Benson and Hal Hastings have been sailing in torpedo submarines a while now. But, there is new danger that they will have to get used to, having the actual torpedoes onboard! They will be trying out a new boat, named after Hal, with the Navy watching closely. But trouble is always close by. (Ann Boulais)

It is a wonderful December day in Spruce Beach, FL, and everyone is waiting, waiting for something special that has been promised.

However, King Louis has decreed that an "hour book" be made for his bride, Lady Anne, which in turn causes the Abbott to refuse Brother Stephen's request to leave the brotherhood as his illuminations are the most beautiful, and as such, he desires that Brother Stephen should be the one to make the hour book. This decision angers Brother Stephen. Will Brother Stephen stay at the abbey and carry out his task or will he refuse and bring about a ban against him, a serious matter indeed...
