Excerpt
Green fire erupted out of the masts as the balloon inflated. The airship slowed its plummet and evened out, gliding forward just above the canyon.
Alex heard a loud thump at mid-ship as Mo crashed to the deck. He didn't seem to care about the descent, and rose to his feet to attack a crack that had burst in the main mast.
Most of the griffons were content to let the ship fall, but some had chased the vessel down. These quickly caught up with the airship and resumed their attack on the cables and balloon.
Alex had worried this would happen, and shoved forward the lever that controlled the tail, sending the airship into the canyon.
"This is stupid," Alex said. "This is stupid."
The air thickened near the canyon floor. Alex kept the wheel steady, subtle changes in the tail and wings to keep from scraping a wing off or plunging into the roaring river racing below the hull.
The canyon narrowed as Alex continued his chant of, "This is stupid, this is stupid..."
   
The griffons struggled to stay close to the airship without hitting the canyon walls. The arch came closer, and Alex wasn't sure if it was big enough to fit the airship through. The gap became smaller and smaller the closer he got.
"This is stupid, this is stupid," Alex said in a higher and higher pitch. "This is really stupid!"
The griffons leapt off the cables and balloon with a shriek of sudden fear as the airship slipped through the gap between the archway and the canyon floor.
"Stupid awesome!" Alex cheered. He took hold of the levers that controlled the gas and the tail, pulling them back as far as they could go.
The ship went vertical, flying into the clouds with the same speed as it had previously fallen. Alex grabbed the wheel and held on like he was riding an out-of-control rocket.
The wheel rolled and weaved, and Alex could hear the snapping of cables struggling with the speed. Mo struck them and looked like he was flying as he leapt from port to starboard tightening bolts and cables. Once Alex planted his feet, piloting the ship at a horizontal position with the horizon, he looked down and saw the few griffons who'd stayed with the ship fading into the distance.
Up ahead Alex saw a thick layer of endless clouds. He held his breath as the ship cut through the clouds like a submarine breaking the surface of the ocean. With nothing but blue sky overhead and a sea of white below, Alex pulled the levers to a central, locked position, held the wheel still, and steadied the airship into a level flight. He braced his hands against the spokes of the wheel, staring at the sky as his knuckles turned white. Alex took two breaths, kept his eyes wide to the sun-kissed clouds, and raised his fists in the air to shout, "Yes!"
