stellar sunscreen for face- sensitive skin friendly, feels good not greasy on, timeless
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
I used to try out different brands and this is the one I've got to have for my face- safe on sensitive skin and just feels really nice and not greasy putting on, sometimes I get stuck borrowing so now I get a few and have them in various places. Also, I appreciate they don't change the packaging or add other versions so I can grab and always feels great and works on

Works great but does not hold up to sweat
Size: 3 Fl Oz (Pack of 1), Style: SPF 50
Dissolves with intense exercise then burns eyes and makes a mess, but otherwise works great.

A Charming Historical Cozy Mystery
Format: Audiobook
Lady Hardcastle and her companion Florence Armstrong, have moved to the country. They think they’ll find a quiet life, but almost as soon as they set foot into the area, things start happening. Before they know it, they’re involved in helping to investigate two very different murders. They have some previous experience with such things, but will the constabulary take them seriously? I mean, they are women, after all; what cam they possibly know about such things?.
This was a charming cozy mystery, and I can’t wait to listen to more books in this series. The writing was top notch, and the characters a delight. The plot was beautifully developed and executed. All in all, this was a jolly good read. I really enjoyed learning some of the backstory for Lady Hardcastle and Flo.
I listened to the Audible audiobook of A Quiet Life in the Country. I thought it was remarkably well narrated. Truly, I look forward to learning more about Lady Hardcastle, Flo, and their new friends and associates.
I purchased a copy of this audiobook from Audible or Amazon. I can’t remember which. In any case, all opinions in this review reflect my true and honest reactions to reading this book.

What a delight to read!
Format: Kindle
I'm not quite sure what I expected when I plunked down my money and downloaded A Quiet Life in the Country. A modern variation of the Golden Age country house mystery? If that was it, I didn't get it. What I did wind up getting was a whole lot more. I will warn you ahead of time: if you are a fan of those classic mysteries, T.E. Kinsey's book may not be your cup of tea, and now I'll set about telling you why.
Kinsey has written a good, puzzling, multi-layered mystery that gives you a real feel for village life out in the English countryside at the turn of the last century. While the plot and the setting are first-rate, it's Kinsey's characters that make this book shine-- and what makes the book turn away from those classic mysteries.
Inspector Sunderland moves from being a stereotype to being someone rather special, which I always love to see (being sick to death of incompetent policemen in the books I read).
Lady Emily Hardcastle's background is very mysterious indeed, and I hope it takes several books to have all the details teased out for us to see. However, it is the relationship between Lady Emily and Florence that is the pièce de résistance of A Quiet Life in the Country. Their dialogue is so full of mutual admiration, wit, and humor that it is, quite simply, a delight to read. As Sunderland witnesses one such conversation, he asks, "Are you two a music hall act?" and you have to admit that he has a point. (If they were a music hall act, I'd pay to see them.)
If you're in the mood for something that's light and fun, something that teases your brain, takes you to the English countryside of a century ago, and makes you laugh, have I got a recommendation for you: T.E. Kinsey's A Quiet Life in the Country. I'm on to the second book!

are looking to settle in to the nice, quiet
Format: Paperback
Welcome to Littleton Cotterell,a small village in Glouchestershire. The year is 1908, and Lady Emily Hardcastle and her intrepid maid, Florence Armstrong, are looking to settle in to the nice, quiet, retired life after several years spent adventuring around the world.
Naturally, such plans are always disrupted. In this case, the two women discover a dead body hanging from a tree while out on a morning walk. The death is meant to appear as a suicide, but certain inconsistencies seen to point more towards murder. With the local constabulary over their heads, Lady Hardcastle and Flo must draw on their previous experiences to solve the murder before anyone else gets hurt.
The mystery goes off in fairly expected fashion, with the eccentric and kindly Lady Hardcastle relying on her witty and resourceful maid. There are suspicious characters and red herrings aplenty. And, naturally, the initial mystery gets wrapped up in several others in the course of the book.
I will say this for A Quiet Life in the Country: it does not take itself too seriously. The usual tropes of the cozy mystery are addressed with a wink and a nudge (such as one character explaining to Lady Hardcastle that the tiny, 30 person village she just moved to is actually the murder capital of the country). I appreciate the effort made to acknowledge all the commonly used bits that go into a cozy murder mystery, and it certainly helped to dispel a feeling of deja vu.
In all, if you’re looking for a nice, quick mystery with not one but two strong female leads, you could do far worse than to join Flo and Lady Hardcastle on their adventures.
A free copy of this book was provided via Goodreads Givaways in exchange for an honest review. A Quiet Life in the Country is currently available for purchase (and, at the time of this writing, free via Kindle Unlimited).
