The middle of the Beginning

Starting with book two I really want to start each book right in the middle, or more accurately right in the climax, of mini adventure. I want to show that time has gone on since the last book and we simply pop in and have to catch up with Michael and the gang. I sort of want it to be like the Indiana Jones movies that always start at the end of one adventure and the beginning of another. with these there will be a whole sub cast of villains, a tier 2 rogues gallery if you will. Dr. Melodian is the prime villain of 'City Under Seige along with his three henchmen; Sonic, Hawk, and Hammerhead, but the book starts with Titan the evil twin brother and sister shock and Awe. they are a little too into destroying property with explosives. I will use some of these mini battles to even bring back returning villains as well. Some of the other sub cast of villains will be: the Claw, Shockwave, and the Ice Queen. Needless to say Titan will have his hands full.
