The Ultimates's headquarters have been broken into by a quintet of people claiming to be from the future (hence the title, tomorrow men), and they bring tidings of a great evil that the Ultimates need to take out today, in order to chance the tyranny of the future. Of all the Ultimates to take these men and their message to heart, Tony Stark finds himself compelled to do so most fervently, especially in light of the legacy that he hopes to leave behind (as well as to the future), but are the tomorrow men on the level? Is the threat they speak of so sinister that they have to follow though? It's up to the Ultimates to find out.
As usual, a proviso: this story assumes that you know the comic book characters The Ultimates. They are: Tony Stark (Ironman), Nick Fury (head of The Ultimates), Steve Rogers (Captain America), Jan (the Wasp), and Thor. In addition, there are new additions to the roster of The Ultimates, Natasha Romanov (the Black Widow), Hawkeye (black ops specialist), Wanda and Pietro Maximoff, who have a very close sibling relationship. In addition, this book seems to take place during the period when Stark and Romanov were moving towards a relationship, so if Stark seems a bit of a sap (he's always this way when it comes to the women in his life, whatever the Marvel Universe. True story), that might be why.
This novel was okay, in that the story was interesting enough to follow to the end, but it wasn't as good as Against all Enemies in that the plot seemed to falter in key moments, and some concepts were a tad wobbly. On the plus side, you'll appreciate how the writer recognises that Stark, Banner and Pym are brilliant men, in spite of their personal foibles. If you put this book in your amazon basket, you won't be upset, but it's not the better Ultimates novel out there, pity that.
