This was a fun story of Q giving Picard and Crusher a gift on the eve of their wedding.
As tends to happen in the Star Trek literary world, a minor character is brought back to play a role in the story. This is part of the fun and serves as a tip of the hat to fans who might remember the character in question.
The story was charming and the pay-off was well done. My only complaint was the lack of Q in the story. He's there to get the story started and at the end but otherwise he was nowhere to be enjoyed.
