The references to the Typhon Pact in the books like Losing the Peace, Over a Torrent Sea, and Full Circle are just passing mentions that it exists. Since you already know that it exists, that won't spoil anything for you.
I'm currently reading the Titan series. I'm in the second book of the Destiny series now. After "Destiny" I was told to read "Over a Torrent Sea", "Synthesis" and "Seize the Fire" (Typhon Pact #2) then the newer Titan books.
Is that the right reading order? And do I need to read the entire Typhon Pact series or is the Titan crew only in that one book?
