Forum:Book of moon vs Gemini Summon

If I were to try to Gemini summoning, could my opponent use book of moon to flip my monster face-down? Gemini Summon is a Ignition Effect? (because if I "give" my Normal Summon, it could to be trated like a cost and this way my Gemini Monster can become a Effect Monster), Please, clear me this question.
