Buy it. Read it. You'll love it. I just finished it last night, but haven't gathered all my thoughts to write something. I woke up this morning wondering how Sally is doing, though. It's a set-up for an ongoing series if I've ever seen one.
I was trying to compile a list of 'types' who would enjoy and/or glean from and/or be validated in reading this book. So far, this is what I have [NOT in any particular order!]:
1) Love Brit humour
2) Love to/not embarrassed to laugh out loud
3) Not embarrassed by their own tears
4) Lost a spouse or someone VERY dear, be it a partner, significant other, or friend
5) Recently divorced [loss not requiring death]
6) Love Hydra
7) Love Leonard Cohen

Value incisive insights into human nature and human experience
9) Love reading a story where it's not all laid out for you ahead of time, but rather where you experience the element of discovery, as the details of the story loop back on themselves and, in doing that, what has happened comes clear.
10) Enjoy a forward-moving story
11) Love writing that is RICH with detail
12) Love irony, wit, and down-to-the-ground honesty
13) Appreciate the sometimes relative frailty of our emotional selves and how we do our best to cope with that reality
*** [Add ons]:
14) Women growing older
15) Have neighbours who would not be of one's own choosing
16) Have children, especially who have not followed that 'ideal' linear pathway from youth to maturity that some/most parents envision or hope for
18) Appreciate the contrast in some couples [introvert-extrovert]... both straight and gay
17) Gay or had enough gay friends to recognize some of the other endearing/frustrating traits some have, including being camp
18) Love to travel and love the feeling of coming home
19) Bound for one reason or another to their love of their physical home
Well, I could certainly go on here... their is all but literally something for everyone in this book.

I knew there was a legitimate #20...
20) Love theatrical people

I'm sure I've left something out. I sincerely hope that LadyGrinningSoul [whose screen name I now 'get'] will soon be able to visit Hydra for herself. So far as I could tell, not all details were spot-on about our beloved island, but sufficiently many were to make those that weren't not matter. I also feel much better about the new front cover. Truthfully, I feel it ought to stay in place, but place the nude one on the back cover, where it can be more fully appreciated by the end of the story.
Best regards, LadyGrinningSoul,
Lizzy
