Помогите с переводом)

Hi Masha,
How are you? I'm sorry I haven't written for sometime. I've been very busy. Let me just tell you.
Unfortunately, there is no news about the MacWizards' family history book. Rob and I have given up hope. We are trying to forget about this story. Sometimes I think there has never been any family treasure at all. But Mark hasn't given up yet. He still believes the story about the treasure and with my help hopes to find it.
The good news is that life at school is great. Rob and I are getting really popular; we have joined most of the school clubs and gone on different excursions. We have already been to York, Cambridge, London, and next week we are going to the Houses of Parliament.
I'm afraid my mission here is nearly over and I have to go home in March. Luckily I'll still be here for the excursion to London.
That's my news. How are you getting on? How's Gram у? I often think about her. She taught me English and that's the best present anybody has ever given me. Please say hello to her for me.
I'm sorry but I have to stop now. Rob has just come and called me for dinner.

Hope to hear from you soon!
Best wishes,
Misha
