If your book club(s) have been anything like my past book club, most of the interesting conversation is only tangentially associated with the book. We found ourselves discussing travel, other books and memories the book triggered.
Here's the place to post thoughts triggered by Juno's Daughters but not actually about Juno's Daughters.
JD reminded my mother and me of A Valley in Italy because of similar parenting styles. However, A Valley in Italy was memoir (note to SalSis-- JD is not!) and the author had not suffered the consequences of her laissez faire parenting, or grown, as Jenny had (or at least she did not think that her daughter running off to Paris and getting married at 17 while she [the mother] was pregnant in her 3rd or 4th child-producing relationship was suffering a consequence of her parenting style).
One friend was reminded of a multi-day party we attend every summer with a band and a gathering of wanna-be-hippie types (note to Mom and Prairie Quilter-- we do not run around naked at such party, nor do we indulge in toothpicked brownies [but we are aging enough that the food is typically excellent]).
I was reminded of Prospero's Books (based on The Tempest), Feast of Love (based on A Midsummer's Night Dream, but I did not know MSND well enough to recognize it), 10 Things I Hate About You (the Heath Ledger movie, based on Taming of the Shrew), Snow Falling on Cedars (takes place in the same part of the world, but in a very very different time and under very very different circumstances) and various travels to islands (in Puget Sound and in Scotland).
