The Whens Of Wick - Return of the Wick Chronicles, #1

Wick knows he's old. It's his memory that upsets him. Hovering somewhere around 120 years old, he can't remember large chunks of his life: he'd already forgotten life before living with Jax and only remembered when the transponder planted in his brain was activated. But now, with Will happily married and expecting his first child with Aisha, Wick realizes he needs to know where he came from and how he began.
In the Return to the Wick Chronicles, Wick remembers an important detail: a boy named Tad who had, in another lifetime, fed and cared for Wick when he was struggling to survive on his own. With few details to go on-a U. S. President hung in effigy and men lighting suckers on fire-Will thinks he knows the first When to visit and takes Wick on a journey to find Tad, find himself, and learn how he came to be.
