Here is the summary of the book:
Until the day I met John Smith, Number Four, I'd been on the run alone, hiding and fighting to stay alive. Together, we are much more powerful. But it could only last so long before we had to separate to find the others. . . . I went to Spain to find Seven, and I found even more, including a tenth member of the Garde who escaped from Lorien alive. Ella is younger than the rest of us, but just as brave. Now we're looking for the others--including John. But so are they. They caught Number One in Malaysia.
Number Two in England. And Number Three in Kenya. They caught me in New York--but I escaped. I am Number Six. They want to finish what they started. But they'll have to fight us first.
The battle is drawing ever nearer. After the events of 'the power of six' in here we see Six found Seven and Ten, a bonus for her in Spain along with the Cepan of Ten, Clayton. While Four is with number Nine. The group with Six goes in search of number Eight and the others are ever closer to the enemy than they know of. And the enemy is on Earth, Setrakus Ra himself is heading the fight and he is one you cannot tarry with. Our Loric heroes get a taste of it when they battle this particular Mog. A battle from which they barely escaped alive. But who amongst them will be Pittacus Lore???
Just like the previous book....another amazing addition. Out of all the new additions to the cast, I definitely loved the titular character Nine. He is very different than all the characters. Free from captivity, this is one character who brought out a lot of emotions from Four/John. Almost acting as a teasing big brother to Four, Nine raised differently deals with things differently. The action is nail biting and adrenaline inducing as ever. Oh I can't wait for the final battle its gonna be EPIC.
"Aliens, Sci-fi, action-packed, flight for good against evil and EPIC fights -- you can't miss it out"
