Recognizing the Hearts that Burn Within Us
Format: Paperback
Yes, Theo of Golden does, at times, border on the melodramatic and the sentimental. It can be repetitive. It can take an awfully long time to make its point. And yet, the novel speaks very significantly of the need for love, compassion, generosity and forgiveness---in a world that is not always kind, in a world where many of us carry secret burdens---where sadness (mixed with intermittent joy) might be viewed as a universal human affliction.
Theo of Golden is, overall, a book of glad tidings. An end with a future. Thoughtfully, warmly and intelligently written. A novel that often addresses the beauty of Art, most notably painting and music. A novel in which I learned what a fado is. In fact, I learned a lot from this novel.
Unlike some readers, I did not see the book as misogynistic or xenophobic. I didn't necessarily see it as "Christian fiction"---unless you mean doing good, striving for strength of spirit and understanding the connection between "the ultimate and the proximate, the wide grace and the narrow way."
Finally, I don't view the novel's conclusion as disappointing, but simply as falling action and resolution. It is, after all, a very traditionally structured work.
Kudos to the author Allen Levi for having written an initially self-published book that was later picked up by a major publishing house. That is, indeed, a rarity.

Sparkle easy tarpaper towels gets the job done
Package Size Name: Double, Size: 6 Double Rolls (Pack of 1), Package Size Name: Double, Size: 6 Double Rolls (Pack of 1)
Performs as described. Not as durable as Bounty but is worth the money. It is soft. Appearance is noted with a design. The quantity is appropriate for each roll and for the price. I use for clean ups in the kitchen, light spills and clean ups. Would buy again. Have purchased many many times. Reliable and consistent company the towel tear off easily every 8” which is a great way to avoid waste especially when cooking.

I'm going back to Sparkle
Package Size Name: Triple, Size: 3 Triple Rolls (Pack of 1)
I used to buy Sparkle years ago , it was the only brand I bought, but I stopped because they were lower quality than names like Bounty.
Recently, before payday I ran out of paper towels and bought this pack before payday so I didn't have to shell out $25 for paper towels.
Sparkle i can honestly say has improved immensely in quality, yet still staying reasonably priced.
I noticed as soon as I opened one roll it was better quality. They are stronger, much stronger than they used to be.
No loose lint like they used to have. They are a bit stiffer in feel compared to Bounty, but still feel soft.
Cleaning is the real test for me. The old Sparkle shredded apart as soon as I wet the towel to clean.
The new Sparkle is amazing. Gotta say I like it better than Bounty. I used it to clean the bathroom and the towels held up extremely well with being water soaked, used to scrub
(friction & pulling). They don't feel thick which i like.
Reusable? I'd dunk the towel in water, scrub then rinse the towel and wipe and it held up .
Sparkle has improved and won me over!

Great value.
Package Size Name: Double, Size: 6 Double Rolls (Pack of 1)
Excellent value for the money. They are not the most thick or soft. But they are better than some. It’s a good middle of the road towel. A very durable paper towel for various odd and end cleanups.

House staple
Package Size Name: Double, Size: 6 Double Rolls (Pack of 1)
These Sparkle Pick-A-Size Paper Towels are a great everyday household staple. I really like the pick-a-size option because it helps reduce waste when you only need a small sheet for quick cleanups. The towels are absorbent, durable, and strong enough for kitchen messes, spills, counters, and general household cleaning without falling apart easily. They also tear cleanly and fit standard paper towel holders well. The rolls lasted longer than expected thanks to the smaller sheet option. Overall, a dependable and budget-friendly paper towel choice to keep stocked at home.
