OK. solve this:
This is the book to buy for all your vegan and vegetarian friends and family members. It is easy to read and to use... has great recipes and handy hints in a novel layout - and the best part of all is that everything tastes delicious! Some vegan recipes might be healthy but they are not always as tasty as the 'original' Not so with this book! Bryanna's book is filled with recipes ranging from basic cooking instructions to exotic desserts... all yummy and all relatively easy to make.As an added bonus, Bryanna gives lists of mail order resources for sometimes hard to find items - this is especially valuable if you are like me and live in a rural area without easy access to health stores.If you buy just one recipe book this Christmas season, this is the one to get! If I could give it six stars I would!
Answer:
Positive
