Maximum Ride
Maximum rideIt had genetic children but I only ready one book, maybe it's one from that series. The first book in the series, The Angel Experiment, gives a brief overview background into the story.
The first book in the series by James Patterson gives an overview of the Flock: Maximum Ride (the leader), Fang, Iggy, Nudge, Gasman, and Angel. These children, ages 6 through 14, are far from normal. They are only 98% human, while the other 2% is avian, giving them wings and special power, with altered body characteristics. This book covers some of the back story of the Flock, explaining how they ended up on their own in their remote mountain home. It also covered the antagonistic half-wolf, half-human creatures known as Erasers.
