The Bluest Sky is the story of Hector, a Cuban boy in 1980 who dreams of getting on the National Math Olympiad Team. But he wonders if the politics of his father, who spent time in prison and now lives in America, will outweigh that of his grandmother, who is a high official in the Communist party.

There are rumors that the government is allowing more people to leave Cuba. But they are rousing communities against the non-patriotic scum who would do so. Hector loves his country and his friends and doesn't understand why anyone would leave.

And then his mother tells him that she has applied for exit visas to join his father, whom Hector hardly knows.

The story that follows is full of ups and downs and conflict. It builds toward the Mariel boat lift, when Cuban prisoners were added to the boats of refugees.

This book is a window into a difficult time and tough decisions. I had heard of the Mariel boat lift, but hadn't realized it was so recent - and that Hector would have been younger than me, so folks from that episode of history are still alive in America today. I appreciate that fictional eyes can help kids understand what it must have been like to live that historical moment.
