"Savage World" is good but not amazing follow up to "out of time". It is a lot slower than "out of time", spending lots of time with future flash trying to blend in as present flash. The story is kind of a redemption ark for future flash. I wont spoil what present flash gets up to but his story is all about getting home. Over all this book is a long epilogue to "out of time" that has a grate tease at the end.
