Excerpt from The Good Father by Noah Hawley, plus links to reviews, author biography & more

Fran was a virtual assistant, which meant she worked from home, helping people she'd never met schedule appointments and make flight reservations. Instead of earrings, Fran wore a Bluetooth earpiece, which she put in when she awoke and didn't remove until just before bed. This meant she spent large portions of every day conducting what appeared to be a long conversation with herself.

The twins, Alex and Wally, were ten that year. They were fraternal and not in any way similar. Wally had a harelip and a slight air of menace about him, like a boy who is just waiting for you to turn your back. In truth, he was the sweeter of the two, the more innocent. A miscoded gene had given him a cleft palate, and though surgery had mostly corrected it, there was still a quality to his face that seemed off-kilter, imprecise, vulnerable. His twin, Alex, fair-haired, comparatively angelic looking, had gotten into some trouble recently for fighting. It was a familiar problem for him, starting in the sandbox era as a willingness to battle anyone who made fun of his brother. But over the years, that instinct to protect had evolved into an irresistible need to champion the underdog - fat kids, nerds, kids with braces. A few months back - after being called to the principal's office for the third time that semester - Fran and I took Alex to lunch and explained to him that while we approved of his instinct to protect the meek, he would have to find less physical ways to do so.

"If you want these bullies to learn a lesson," I said, "you have to teach them something. And I guarantee, violence never taught anybody anything."

Alex had always had a quick wit and a sharp tongue. I suggested he sign up for debate classes, where he could learn to beat his opponents with words.

He shrugged, but I could tell he liked the idea. And over the next few months, Alex became the top debater in his class. Now he turned every request to eat his vegetables or help with the chores into an Aristotelian voir dire.

I had no one to blame but myself.

This was our nuclear family. A father, a mother, and two sons. Daniel, the son from my first marriage, had lived with us for a year during his sullen teens, but had departed as impulsively as he'd arrived, waking me one morning before dawn to ask if I could drive him to the airport. His mother and I had split when he was seven, and he had stayed with her on the West Coast when I had come east.

Three years after his brief stay with us, Danny, eighteen, had started college. But he dropped out after less than a year, climbing into his car and heading west. Later, he would say that he just wanted to "see the country." He didn't tell us he'd left. Instead, I sent a card to his dorm, and it came back unopened, with a stamp occupant no longer at this address. This had been his way since childhood. Danny was a boy who never stayed where you left him, who popped up in unexpected places at unexpected times. Now he called infrequently; sent e-mails from Internet cafes in the flat states of the Midwest. The occasional postcard scrawled in a moment of summer nostalgia. But always at his convenience, not mine.

The last time I saw him was in Arizona. I'd flown in for a medical conference. Daniel was passing through on his way north. I bought him breakfast in a hipster coffee shop near my hotel. His hair was long and he ate his pancakes without pause, his fork moving from plate to mouth like a steam shovel.

He told me he'd been doing a lot of camping in the Southwest. During the day he hiked. At night he read by flashlight. He seemed happy. When you're young there is no more romantic conceit than freedom - the boundless certainty that you can go anywhere, do anything. And though it still bothered me that he had dropped out of college six months earlier, knowing him as I did, I can't say I was surprised.

Daniel had grown up traveling. He was a teenage gypsy, shuttled between Connecticut and California, living partly with me and partly with his mother. Children of joint custody are, by nature of the divorce settlement, independent. All those Christmases spent in airports, all those summer vacations shuffling back and forth between mom and dad. Unaccompanied minors, crisscrossing the nation. Daniel seemed to survive it without major trauma, but I still worried, the way any parent does. Not enough to keep me up at night, but enough to add a layer of doubt to each day, a nagging sense of loss, like something important had been misplaced. And yet he had always been self-sufficient, and he was a smart, likable kid, so I convinced myself that wherever he went, he was fine.
