Extreme Danger is the first book in The Hardy Boys: Undercover Brothers series by Franklin W. Dixon.

There is a mysterious person—known as Mr. X—who tries to sabotage the Big Air Games. The victims are top extreme athletes in the country, as well as thousands of spectators. And there may be a group of extremists working together. Or there may only be one. Frank and Joe, who work for the A.T.A.C. (American Teens Against Crime), must work out the person who is trying to sabotage this event.

I ;OVELOVELOVELOVELOVE this book this was the first hardy boys book I ever finished but the first one I read was speed times 5 (also there is some similarities between this and that) this is a reboot of the franchise but never takes it to the level where old time fans wont like it so the story is that some one is sabotaging the Big Air Games and two teenager boy Joe and Frank Hardy(as Frank and Joe put it Frank is the logical Hardy and Joe is hardly logical) gets sent by the agency they work for ...more

I've been meaning to start reading this series in order for a while now, and I'm finally getting around to it. This book was read in its entirety on a day-long bus trip, and like any good book, it was a great way to pass the time.

I'm still a little confused as to how the culprit's motive was supposed to work. Not to mention a little surprised at the culprit himself. But I guess that's how it works, and it does make sense when I think about it.

Anyway, great book. I already read number two, so I'm

Such a nice book. My logicity exploded as soon as I entered the realm of the Hardy's.
Frank and Joe go undercover for ATAC at an extreme games competition. Sabotage is happening and a creepy reporter keeps showing up just when someone is injured. An annoying guy who runs the best skateboard shop ends up dead. Things are getting worse until Frank and Joe finally realize who the real bad guy is.To make it more confusing, there is even another undercover ATAC agent who's also on the case, that Frank and Joe don't know about. Good mystery.
James Bond similarities made me laugh. I found that the writing style was stilted. It is rated at a grade five level; however the author tended to throw in words that are not easily understood by students reading at a grade five level.
This book was really good. It has all the genres you need in a great book; murder, mystery, detective. I would recommend this book to anybody who is a mature reader.
this book was good i am glad i read this because i can be a good undercover for other plople and help others. that what this book showed me.
Very 1st book in this grouping. They boys nearly die skydiving and then get sent on another mission soon after.

3.5 The perspective/narration switching between the brothers was a bit confusing, but a series I think boys will enjoy.

This book rocks .
I like this Hat=rdy Boys
It was my first Hardy Boys book. Frank and Joe are really good and brave ATAC officers.
Reading in between some serious book. A laidback. A mind recreational drugs.
