Wéber Anikó - Marci and Merkúr - Űrlény az osztályban

A new kid arrives in the funnest class, who introduces himself only as Mercury. He has a planet blooming on his pen holder, throws Morse code on the table in hours, calculates as fast as a robot and claims to have his own space station. Marci gets suspicious and starts investigating after Mercury... But even if the truth is revealed, Marci, the person in charge of fun, has the most difficult task yet to come: how will everyone be happy again in the funnest class?
Now I'm reading! The adventures of Marci and the funniest class, popular in the series, continue in a longer novel, already for fluent readers, but still in large letters, with many pictures, easy to read.
