Dr Jekyll and mr HydeWatch
I did Jekyll and Hyde for GCSE and it can be a tad challenging/boring if you're not used to the language of the time. I think you're definitely doing the right thing by making summaries. The first few weeks of learning this at school will largely be writing summaries, so you can simply add to and improve yours. I honestly found the book fascinating and I still have it on my bookshelf! I did the same as you and went on to receive an 8 (darn you Romeo and Juliet for costing me my 9!!) so this is a good start to strong study habits for your English and I defo recommend you keep it up!
The writing is very rich and full of literary devices. Pathetic fallacy is everywhere: I tell my students that the weather is almost a character in its own right. What the text is missing is any real female representation but this is something you can consider for social and historical context.
You'll be an expert in eighteen months time and you've started very wisely.
