'Delayed reader' syndrome

My grasshopper memory means I can't easily read WIPs. I need that 'in our last thrilling episode/ manga chapter/ tankoubon/ volume' reference for absolutely everything. I do want to read the ending of FMA, but I hesitate because it involves reading the last ten vols of FMA. At least. And every new Aaronovitch requires rereading the previous Aaronovitch. At least. And so on.
