Ronni-Romario and the Soccer Planets - Earth Versus Neptune

Once there was a time when humans and aliens lived separated from each other.
Now, soccer has united them.
Ronni-Romario plays on Team Earth which is an 11-player soccer team. The first match of the Solar System Championship is to be played on their home turf, but can the team beat the aliens from Neptune who are both older, faster and stronger than themselves?
Ronni-Romario and the Soccer Planets - Earth Versus Neptune is the first book in a space adventure series about soccer, team spirit and friendship.
Ronni-Romario and the Soccer Planets are the coolest soccer books in the universe.
