One arm of manga publishing that has been popular for decades is Sports Manga.  These are mostly popular with the gentlemen readers, but I have seen a number of  young ladies gravitate towards sports manga.  There are so many titles encompassed in this genre, and a lot of the good ones are really hard to find now (Initial D comes to mind, which was published by TokyoPop, so good luck finding those).  New series are coming out all the time in this area, so check with your readers to see which ones they might be interested in.

As the title gives away, this series is about a tennis player.  Ryoma Echizen is no ordinary tennis player.  He's only 12 years old, but he's good enough to compete in the 16-year-old tournament and wipe the floor with all of them.  How can this pip-squeak be so good??  Well, his dad was a major tennis star, and his talent was genetically passed on to his son.  The Prince of Tennis is a title others have pushed on Ryoma, and each volume is filled with ways he has to prove to others that he is worthy of that title.  Ryoma also enrolls in an Academy for rising tennis stars, so the pressures of school are added to the demands of tennis-playing.  

Joshua Williamson is responsible for the character of The Flash in the DC Universe Rebirth event, and he does a stellar job.  A word to the wise: Flash is a character that can be hard to follow.  Flash's abilities, similar to Superman in the 1978 movie, allow him to time travel by running really, really fast.  So there are a lot of time and space jumps, and a lot of those jumps include references to other storylines in other comics.  Not to worry - this doesn't mean you have to buy all of them.  Savy readers can use context clues to figure out characters they don't know, or there's always Google.

Anyway, to the actual review now.  These Flash books start off with a ton of other Flashes and how Barry Allen not only has to cope with other super speedsters, but how he has to train them to use their powers for good.  At first it's great.  Barry doesn't have to be everywhere saving everybody, but of course all good things must come to an end.  Some of his students break off from his altruistic teaching and fight against his good intentions.  Compounded on that, some old enemies creep back up, and Barry definitely has his hands full in a time he thought he'd get some more sleep.
