I've been impressed by Michael Roberts's blog posts, on the right sidebar here in the web view. He is insistent that lack of profitability is both the proximate cause of crises and the underlying reason for long depressions, such as the one we're currently experiencing. He is also prepared to make predictions.
So this seemed to be the book to get (published in July 2016) to learn more about his thinking. Here's the Amazon summary.
"Setting out from an unapologetic Marxist perspective, The Long Depression argues that the global economy remains in the throes of a depression. Making the case that the profitability of capital is too low, and the debt built up before the Great Recession too high, leading radical economist Michael Roberts persuasively presents his case that this depression will persist until the profitability of capital is restored through yet another slump."
Here is Michael Roberts talking on "Economic crisis and the long depression" at Marxism 2017:

I'll let you know what I think: it's competing with Steve Keen's book and Capital Vol 2 at the moment. But I think it's a priority.
