Found this article from a couple of days ago about this
children's book called, "Donovan Twins: Olympic Mind Games", by Robert Ronsson.
Despite warnings of possible legal action 300 copies were printed.
Set in 2012, in London's Olympic Village, the book is about twins who are the first contact with aliens and who must save the world from
destruction.
The book is the first in the Roswell File series featuring the Donovan twins.
Under the London Olympic Games and Paralympic Games Act 2006 organisers have trademark rights over words such as "Olympic" or "London 2012" or
"2012" to stop companies from using them if they are not officially licensed.
