Mark O'Sullivan

His name is Jimmy. They told us not to call him Dad any more. It might freak him out.<br/>
The accident changed everything. Once, my Dad was the perfect father. We were the perfect family. Now he's got the mind of a ten-year-old.<br/>
From one crazy day to the next, we lose a little more of the man we knew and loved. <br/>
And then a shocking discovery about his past makes us question everything . . .
