thanks AlPe and DiapDealer,
I tried lekts and it is awesome but unfortunately its doesn't support making notes, highlights and share for text.
I know there is a great tool like iBooks Author which has a lot of features to create rich interactive ebook but unfortunately it works on ipad and ibooks only , and the client need his book to work on any os !!! so I think epub3 is the best solution but my problem is the epub3 reader!!
I think readium is the best reader for pc but I still can't find a great epub3 reader for Ipad.
