Hello Ann
How are you? Thanks for your letter and sorry for taking me too long to write back.
First of all, I want to say that I received your book and already read it. Honestly, I did not even expect that it can be so interesting! The plot really impressed me.
Вut I write to you for another reason.I would like to know about your biology lessons at school. Which teacher you have- a husband or a woman? Are the lessons interesting or perhaps boring?
What are you doing at lessons?
Please tell me more about it in your next letter.
Hope to hear you soon.
With love, 
Arina
