An incredible guide for your Advent journey.
Format: Paperback
Thank you Miriam for bringing us this beautiful and deep guide for our Advent journey. I used it for the first time in 2023, and will definitely be using it again in 2024. I loved and looked forward to every day that I sat with the daily passage.
Miriam guides us into daily Scripture, and includes questions for us to meditate on and apply those passages. In addition, she adds her own meditation, which offers a rich perspective. It is accompanied by Lilias Trotter's own perspective through her words and wisdom and gorgeous art. The author invites us into self-reflection multiple times through each daily passage and includes poetry and song that binds each daily message.
I will definitely give these as gifts for next year, and I am so looking forward to walking through it again next Advent. It will be interesting to see the Lord's living and active wisdom reveal itself year after year.
I would highly recommend keeping a journal as you dive in to this rich, rewarding journey.

Good news, bad news.
Format: Paperback
I like the product, but because it was inadequately packaged, the top of the book is imperfect. It's certainly readable, but if I am paying full price, I expect a perfect copy.

Deep Into the Financial Nuts and Bolts
Format: Paperback
This a very, very informative book about the financial crash of 2008 and its lengthy recovery. The British author is a fine writer and definitely appears to master the subject. His background is as an economic historian and his approach to the financial collapse is thru the lens of political economy.
For a European, he is very charitable towards the failures of the US markets and the responses of the US govt in the crisis. In fact, he is much more critical of the Germans and the British and the EU govts in their involvement in the crisis and their failure to more effectively guide the Eurozone out of the financial crisis.
The book is somewhat dense and daunting and is 616 pages of text. Definitly not for the faint of heart or those who are not somewhat financially and economically literate. It does not lend itself to speed reading. A glossary and list of abbreviations would have been very helpful--as other commenters have suggested. Abbreviated acronyms of organizations, treaties, agreements,govt agencies, etc. come flying fast and furious. Still, with due and diligent effort on the part of the reader, you can see how very well the author knits his technocratic financial narrative together.
The negative reviews often seem poorly informed. It's a difficult book to get thru. Some readers appear to dislike the author because he is a Keynesian liberal. I understand that, but they should note that he tends to be very positive about US govt financial leadership leading the world out of the crisis. Some don't like the fact that he thinks Trump is a grifter. Unfortunately, Trump is, irrefutably, a grifter and a con man.
The only areas where I found myself disagreeing with the author were on the issues of immigration and protectionism. The Eurozone and the US cannot support unrestricted immigration. There are too many millions in the world of 8 billion people who would kick down the gateways of either entitity to gain entry. Unrestricted immigration is an existential threat to all the Western countries involved. Sober assessment of reality is something other than "racist". "Realistic" is a far more accurate term.
The author is a classic liberal and against national "protectionism". However, this is 2023. The book was written in 2017. Much water has passed under the bridge since then. Countries are political entities with borders. Too often--as the writer points out--economic and financial advisors forget the "political" part of "political economy". Trump's legions are there to remind them. At least they are good for something. Protecting your economy from essential foreign supply chain failures and from hostile foreign competitors is just good governance. And insuring that others share in general prosperity besides coastal elites is another part of good governance. "Flyover Country" is every bit as important as the two coasts. Probably more so. Never forget the "political" part of "political economy".

A Complete Autopsy of the 2008 Financial Crash and the Government Response
Format: Hardcover
First, let me say that I can't believe one person wrote this entire book. Tooze handles everything - economics, finance, politics, diplomacy, public policy, housing, discrimination, trading platforms - and does it expertly. The author's detailed understanding of such a wide arrange of topics is dazzling, especially his handle on inscrutable national bank mechanics.
Second, if you want a macro understanding of how governments responded to the 2008 financial crisis and how these responses produced such wildly differing results, read this book. The analysis at times is like eating sawdust and it is excruciatingly detailed. There were entire chapters on the European side of the crises that I felt were repetitive and could possibly be removed from the book without losing too much. However, clearly Tooze has done his homework and the data underlying his conclusions is vast.
Third, I learned a lot and I had previously read "Too Big to Fail" by Sorkin and some other lesser known books on the recession. Tooze handles everything from a policy perspective and his data support his overarching theme: the US had a cohesive, massive stimulus program that probably could have gone further, while the EU responded in nibbles. The US rebounded well, albeit not perfectly while the EU went from crises to crises. He also shows that there were massive consequences from the bailout of the financial system: Brexit and cartoonish clown politicians like Trump in the US, and Farage in the EU, who are supported at their roots by a dangerously racist and nationalistic surge of those left behind by the modern global economy. This is an excellent read.
