The Summer Son by Craig Lancaster.
He's the author of 600 Hours of Edward and Edward Adrift.
Quote:
“When Mitch Quillen’s life begins to unravel, he fears there is no escape. His marriage and his career are both failing, and his relationship with his father has been a disaster for decades. Approaching forty, Mitch doesn’t want to become a middle-aged statistic. When his estranged father, Jim, suddenly calls, Mitch’s wife urges him to respond.”
Mitch isn't such an engaging character as Edward, but it's a good read so far.
