Behind the name GardenStone hides a Dutch author who, with the choice of that name, both tries to protect his private life while making it clear that his nom de plume is a pseudonym. At home in the beautiful Taunus Hills in Germany he actualizes his writing projects, which almost all employ in-depth research based on serious attempts to maintain a high scientific level. Nevertheless, he does not see academically educated people as his primary audience. Because he hopes to reach a much wider reading public, a strong accent of his books lies in the use of conversational language and effortless reading. With the little book about Eostre or Ostara one of his minor projects is realized.
