Hello Pam,
You will just love the Rhine river cruise. Will you be there for the Rhine fireworks? Weather-wise we have had a terrible rainy spring, and summer beginning..but I think that is over with. The clouds look exhausted. .-) Usually the weather is hot in August, and we have been having beautiful warm Septembers the past years. In the evening it can get cool, so it doesn't harm any to have a windbreaker with you.
I sent Avalon my query. My book is too long for them; 98,000 words. But thanks for the tip anyway. I'm going to check your book out on Amazon...and probably order it.
