love with A

It had been a long time since I had read a love story as beautiful.
That of a father who tells his son how he loved his mother, Paz, and how, despite the promise he had made to no longer leave Europe, he will go looking for him.
A story carried in the manner of a thriller, since Caesar will investigate to discover the truth about the disappearance Paz. Taking and poignant. The hardest part for me was to close this book.
