I loved '13 Little Blue Envelopes,' and am more than happy to recommend to adults and kids alike! A prior reviewer commented this sounded vaguely like another book, which sounds to me like comparing every tale of star-crossed lovers to 'Romeo and Juliet.' What Johnson has done is taken an idea we've all had at some point -- what if you got a windfall and the opportunity to travel and enjoy it? -- and crafted a genuine and romantic story of a teen's first real adventure outside her comfort level. Ginny would have never gone to Europe without the envelopes -- would have never fallen in love, sponsored an artist, or learned her aunt's secrets. The progression from Envelope #1 to the end shows her growth as a person, as she responds more quickly and more creatively to the challenges in each subsequent letter. I can't wait to read more by the author!
